Mahnabu, Twice Ensouled

When Mahnabu enters the battlefield, put two
different counters from among trample, haste,
vigilance, menace, skulk, lifelink, or deathtouch
onto one or two target creatures you control.
{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 any colors of those cards.
(No colorless mana this way.)
