Mahnabu, Twice Ensouled

different counters on one or two target creatures
you control from among trample, haste, menace,
skulk, flanking, lifelink, deathtouch, or wither.
{2}, Exile two target cards with converted mana
cost X from one or more graveyards: If you own
any of the exiled cards, add {x} to your mana pool
in any combination of only colored mana, in any
of the colors of the exiled cards.
