Rhotan, Sky's Benevolence

Flying, trample, haste
Whenever Rhotan, Sky's Benevolence or another creature enters the battlefield under your control, draw a card, then discard a card. If a creature was discarded this way, you may pay {x}{g}{r}. If you do, create a token copy of that creature, except it enters the battlefield with X +1/+1 counters on it and gains trample and haste. Sacrifice it at the beginning of the next end step.
