Miko's minions

Haste, trample.
Miko's minions gains +1/+1 for each other red
and/or black permanent you control. When
Miko's minions deals damage to a player,
exile the top card of their libary faced down.
When Miko's minions die, until your next
turn's end step, you may play cards exiled with
Miko's minions and spend mana as though it
were mana of any colour to cast those spells.
