Neriv, Heart of the Storm

At the beginning of your upkeep, return up to two target creature cards with power 2 or less from your graveyard to the battlefield. Put a +1/+1 counter on each of those creatures.

Search your library for a creature card with mana value X or less, put it onto the battlefield, then shuffle. Harmonize XGGGG (You may cast this card from your graveyard for its harmonize cost. You may tap a creature you control to reduce that cost by an amount of generic mana equal to its power. Then exile this spell.)

Vigilance, trample, ward 1 At the beginning of combat on your turn, if you've cast both a creature spell and a noncreature spell this turn, draw a card and put two +1/+1 counters on Eshki Dragonclaw.

At the beginning of your end step, you may discard your hand. If you do, draw cards equal to the number of spells you've cast this turn.

Trample Whenever Felothar enters or attacks, you may sacrifice a nonland permanent. When you do, put a +1/+1 counter on each creature you control.

Flash When this creature enters, choose one — • You gain 3 life and surveil 3. (Look at the top three cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) • Destroy target enchantment. • Counter target creature spell.

This land enters tapped unless you control an Island or a Swamp. T: Add G. 3G, T: Surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)

Dragons you control have indestructible. At the beginning of your upkeep, for each color, put a +1/+1 counter on a Dragon you control of that color. If you put +1/+1 counters on five Dragons this way, you win the game.
