This deck makes use of the nice interaction between Eldrazi Spawn tokens and Bequeathal. The problem with using
Bequeathal is, that you often have problems with getting an advantage from it, when you use it on normal creatures.
You need a sacrifice outlet to make it work, and the cost of sacrificing your creatures to draw 2 cards is pretty high,
especially when the opponent always can destroy the creature in response to enchanting it with Bequeathal. Also
bouncing it back to hand or exiling it will deny you your 2 cards. Not to mention how slow this type of deck would be.
Eldrazi Spawns instead can always be sacrificed in response, so there should be no way to deny you your card draw
once you put Bequeathal on it. And if the opponent uses its removal spells to kill it in response to enchanting it with
Bequeathal, its not a big loss because they can't use the removal spell on your bigger creatures. To get additional
value out of it, this deck plays 3 Ironclad Slayer. It returns an aura or equipment cards to your hand and is pretty
strong itself with 3/2 power/toughness for only 3 mana. Also 2 Heliod's Pilgram to search for an enchantment in your
library when it enters the battlefield. There are a bunch of other nice enchantments you can get with it, depending on
your needs: 2 Weight of Conscience, 1 Cristallization for removal; 1 Rancor, 1 Fists of Ironwood and 1 Armadillo Cloak
for trample; 1 Sigil of the Nayan Gods, to draw just a card or for pumping up a creature later in game; and then the
3 Bequeathal for card draw.

This deck runs although 2 Crop Rotations, for some nice surprise effects sometimes. You can fetch for Bojuka Bog
(exile graveyard), Sejiri Steppe (protection), Quicksand (-1/-2 for an non-flying attacker), Khalni Garden (0/1 Plant
token), Kabira Crossroads (+2 life), 2 Haunted Fengrafs (returns creatures from graveyard back to hand), sometimes
you can get just Selesnya Sanctuary for more mana. Although included are 2 Sakura-Tribe Scout, which can give you
instant speed uncounterable land drops, too. But main reason is to speed up building your mana base at start of the
game. This can be a bit a disadvantage if you don't have a Sakura-Tribe Scout in your starting hand and only tapped
lands or Selesnya Sanctuarys. Better mulligan then instead of durdling around for 3 turns doing nothing.

Best start hands are Sakura-Tribe Scout and some lands or one or more early Nest Invaders. Nest Invader should
give you something on board and an additional mana if you need it. Long running games can get sometimes very
grindy when you be able to return things back from graveyard and when you be able to get some card advantage
from your Bequeathals. This all can let you help survive even if it looks very bad for you sometimes, but don't
underestimate the time you need to make all your plays. Running out of time can be a real danger sometimes. Often
a huge help, but although an immense time sink is Sylvok Lifestaff. You can grind out enourmous amounts of life with
your Eldrazi Spawn tokens and turn the game back in your favor again when you don't run out of time before. Matchups
against control decks aren't too bad. Tier 1 is Tier 1, but if you mulligan ultraslow hands you should have good chances
against Mono Black and Dimir Control decks. Against Delver I think it is a bit harder but not really bad. The worst
matchups are in my opinion Elves and Affinity. This decks sometimes get extreme fast hands, and there's no way to
deal with it. With a bit of luck and much removal you still might have a chance to win sometimes against this decks.

The cards:

3-4 ofs:
Nest Invader: a very good card, costs only 2 mana
Kozilek's Predator: a bit expensive with 4 mana, that's why we only have 3 of it
Ironclad Slayer: can give us our Bequeathals or Weight of Consciences back from the graveyard
Bequeathal: much of the deck is build around this card. When you have no Eldrazi Spawns you might cast it on your chump blockers, or creatures you think will get killed soon

1-2 ofs:
Heliod's Pilgrim: only 1/2, but lets you search your library for the enchantment you need
Scion Summoner: another Eldrazi token producer, it produces a 1/1 Eldrazi Scion instead
Blisterpod: cheap 1/1 Eldrazi chump blocker
Sakura-Tribe Scout: allows you to play an additional land each turn, sometimes good for uncounterable land drops
Krosan Tusker: cycles for 3 mana and gives you an additional land card when cycling, big creature for late game, good interaction with Pulse, Haunted Fengrafs
Bloodbriar: can get big with all the sacrificed Eldrazi tokens, cutted down to only 1 because it is often a bit slow and dies easily
Kavu Primarch: convoke creature which can be casted quite early for 4 mana as 3/3 or later with kicker for total 8 mana as a 7/7
Tilling Treefolk: gets you 2 land cards from your graveyard back to your hand, very good sometimes
Citanul Woodreaders: only 1/4 for 3, but draws you 2 cards when you pay 3 more mana as kicker cost
Pulse of Murasa: 6 life and often a good creature back to hand is often a huge advantage
Crop Rotation: can sometimes win games, sometimes its just slow. Also makes our mana base a bit slower, because the spell lands we play enter the game tapped
Sylvok Lifestaff: can grind you enourmous amounts of life with you Eldrazi Spawn tokens. 2 additional in SB against Burn or other decks with much direct damage spells
Weight of Conscience: we play this card as our removal because we can get it back from graveyard with Ironclad Slayer. Don't forget enchanted creature can still block
Crystallization: sometimes we might not have 2 creatures with the same creature type, so we could fetch this instead
Sigil of the Nayan Gods: sometimes fetching this card and cycling it might be better then getting Bequeathal. And when you need, it can pump up one creature
Armadillo Cloak: just a very strong card, often good against decks with no removal
Rancor: for trample, although lets you attack with your small creatures and tokens for quite some damage
Fists of Ironwood: trample and two 1/1 Saproling tokens. Sometimes might be better to enchant opponents creature to play around removal, so you still get the tokens

Sideboard:
4 Qasali Pridemage: against all decks playing enchantments, against affinity, against creatureless decks to replace useless removal
3 Spidersilk Armor: against flyers, sometimes for the toughness boost
2 Moment's Peace: against very fast decks or decks which go all-in with one attack, especially Kiln Fiend, Infect
2 Multani's Degree: against Hexproof
+2 Sylvok Lifestaff
+2 Weight of Conscience
