Lord of Extinction

Exile the top X cards of your library. You may play them until the end of your next turn. Harmonize XRR (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.)

Whenever another creature you control enters, creatures you control get +1/+1 until end of turn.

You have no maximum hand size. T: Add C.

Flurry — Whenever you cast your second spell each turn, put a rally counter on this enchantment. Then create a 1/1 white Monk creature token with prowess for each rally counter on it. (Whenever you cast a noncreature spell, the token gets +1/+1 until end of turn.)

Return up to three target land cards from your graveyard to your hand. Dredge 3 (If you would draw a card, you may mill three cards instead. If you do, return this card from your graveyard to your hand.)

Electrodominance deals X damage to any target. You may cast a spell with mana value X or less from your hand without paying its mana cost.

Return any number of target creature cards with total power 10 or less from your graveyard to the battlefield. Exile Reunion of the House.

Flying Lifelink (Damage dealt by this creature also causes you to gain that much life.) At the beginning of your end step, if you gained 3 or more life this turn, each opponent loses 3 life.
