Tirza, Axis of Collusion

Multicolored spells you cast have conspire.
(As you cast that spell, you may tap two untapped
creatures you control that share a color with it. When
you do, copy it and you may choose new targets for
the copy. A copy of a permanent spell becomes a
token.)
Whenever a creature you control conspires, it connives. (Draw a card, then discard a card. If you discarded a nonland card, put a +1/+1 counter on
that creature.)
