Ride the Avalanche

This spell can't be countered.

The next creature spell you cast this turn can be cast as though it had flash. That spell can't be countered. That creature enters with an additional +1/+1 counter on it.

Put X +1/+1 counters on target creature you control. Then counter up to one target spell unless its controller pays mana equal to the greatest power among creatures you control.

Put a +1/+1 counter on target creature, then double the number of +1/+1 counters on it.

Flashback . This spell costs less to cast this way, where X is the greatest mana value of a commander you own on the battlefield or in the command zone. (You may cast this card from your graveyard for its flashback cost. Then exile it.)

The next sorcery spell you cast this turn can be cast as though it had flash. (It can be cast any time you could cast an instant.)

Draw a card.

As an additional cost to cast this spell, discard a red or green card.

Target creature gains trample and gets +X/+0 until end of turn, where X is that creature's mana value.

Reveal cards from the top of your library until you reveal a creature card. Put that card into your hand and the rest on the bottom of your library in a random order. When you reveal a creature card this way, put X +1/+1 counters on target creature you control, where X is the mana value of that card.
