• Horde has infinite mana
• Tokens count as cards with 0cost CMC and go to graveyard unless they are created by an effect
• You start and prepare for X turns ( Normal difficulty : the horde attacks on turn 4, Earlier = harder)

TIE BREAKER RULES

For random choice :

• Heads or tails if there are 2 options (pay/don't pay, plainswalkers or player, piles for fact or fiction effects)
• Any effect that results in a loss of a permanent chosen by the horde : ( lowest cmc > lowest amount of keywords (creatures) > lowest amount of mana symbols in cmc > rarity)
• Effect that would allow horde to destroy a player's permanent ( Highest cmc > Highest amount of keywords > Highest amount of mana symbols > Rarity)

HOW THE HORDE PLAYS :

• Horde draws and plays the cards until a non-token card is revealed (each action is a single draw for effects like Alms collector)
• Horde may only play 1 non token card per turn (except partner cards)
• All creatures have Haste
• The Horde always attack with all available creatures if able
• If a choice is asked, follow random rules (Pay for Rhystic study, ghostly prison, mystic confluence, etc.)
• The Horde never picks a choice that would kill it ( ex: Pact of the titan, the horde will always pay if able )
• If player controls a plainswalker, horde randomly rolls to attack plainswalkers or not; if plainswalkers are chosen, horde sends 1 creature per loyalty counter for each plainswalkers and the rest attack the player as usual.
• Horde always block in a way to minimize damage received and blocks with lowest cmc first (Follow tie breaker ruling)
• If horde can destroy a permanent or has to lose a permanent, Follow tie breaker ruling
