Selesnya Pentacolor Aggro

>Gameplan

This deck runs on a pretty simple gameplan. Play some multicolor one- or two-drops and pump them fast and by a lot with Glass of the Guildpact and, more importantly, Knight of New Alara, which turns our 1/1s into 3/3s and our triple color-two drops into 6/5s. Thats pretty effective, I must say.

Beaters

We run a wide arsenal of beaters, most importantly Bant Sureblade and Naya Swiftblade. They pump themselves already by +1/+1 and Knight of New Alara will pump them for an additional +3/+3, resulting in a +4/+4 pump, turning them into 6/5. 6/5 at T4 is already pretty good by itself, but gets even better with our multicolor one-drops, as we can spam them on the turns prior, until T4 when they too become good beaters as we play Knight of New Alara. For the one-drops we play Dryad Militant which basically shuts off Snapcaster Mage and Death's Shadow's delve stuff. Judge's Familiar saves us from boardwipes (and Knight of New Alara from being Bolted) and is evasive with flying. Nip Gwyllion doesn't provide much utility but is able to gain us tons of live over the course of the game. Slitherhead is good, as our opponent will be punished for killing it, as it can still pump one of our creatures permanently from the graveyard.

Disruption

For the payoffs we run Glass of the Guildpact, an extremely cheap 2 mana anthem for all of our creatures. The center piece of the deck is Knight of New Alara, representing at least a +2/+2 anthem for all of our creatures.

Control

To kill the opponent's threats or blockers, we play Path to Exile for the best removal in the format. Eladamri's Call helps us getting Knight of New Alara more frequently. I could have included Glittering Wish, but my sideboard is already almost full of colorless silverbullets, so it would be almost completely useless.

Manabase

We play 23 lands, which might seem like a bit much, but we really want to play Knight of New Alara on T4 consistently, and for that matter we need to hit our land-drops. For the budget selesnya mana-base we play Fortified Village, Sunpetal Grove and a bunch of basics.

>Sideboard

For some general sideboarding options we run Knight of Autumn. It's better in grindy matchups, it's good against burn with it's lifegain and it hates against enchantments or artifacts.

Tron:

Against tron we play Ghost Qarter. I don't want to run it main-deck though, mana would be awkward, as our dual-lands require basics to come into play untapped.

Dredge:

When playing against dredge, we will swap out Path to Exile for Grafdigger's Cage, in addition to our previous graveyard-hate with Dryad Militant.

Burn:

When playing against burn, we will not sideboard. We rely on our Nip Gwyllion for lifegain.

Mill:

Against mill we play Tormod's Crypt, which we will swap out for Eladamri's Call and one Glass of the Guildpact. I don't want to take Path to Exile out of the deck, it will kill their crabs and make room for our beaters.

>Budget

The deck is as budget as it gets for a two (or five) color-deck, costing about 45€ on cardmarket.
