Horde Magic: Zombies (Card List)

!! Work in progress, still needs to be tested !!

This deck is created for the 2-4 player coop format "horde magic" (great for 3 players who lack the 4th player for regular edh pods).
Rules for Horde Magic: https://mtg.fandom.com/wiki/Horde_Magic

Quick rule reminder:
20 lifepoints per player in shared survivor healthpool.
[currently testing] While playing non premade decks for this mode and using regular, especially powerful edh decks, create copies of the horde deck for each survivor (2 Players = 2x Horde, 3P = 3x Horde and so on).
Keep in mind that there are many cards that break this format (like Urabrask the Hidden, Silent Arbiter and so on).
The Horde always acts as random as possible but without doing stupid things like bolting a 6/6.
The Horde has haste, inf mana, always attacks and can't block.
The Horde casts from library until a nontoken card is found.

Custom rules we play with:

1. The horde starts after players had 3 turns (noncombat) to build up defenses.
2. When the horde gains life, they shuffle a random card from grave into library for each 1 lifepoint.
3. For each attacker, survivors decide if the creature attacks the library (to mill the horde) or the graveyard (to burn corpses = exile them).
4. If able, the horde uses activated abilites.
5. If the horde appears to be not so challenging, try to modificate it like:

horde turn 1 -> casts until at least 1 creature enters
horde turn 2 -> casts until at least 2 creature enters
horde turn 3 -> casts until at least 3 creature enters and so on.
