Flying
When Azos enters the battlefield, each opponent reveals their hand. You choose any number of nonland cards in players' hands and/or creatures on the battlefield with total mana value 7 or less. Exile those cards and/or permanents.

Damage can't be prevented this turn. Beat & Batter deals 2 damage to target player, then 2 damage to each player that's gained life this turn.

Scry 1, then draw two cards. You gain 3 life. Exile up to four cards from graveyards.

{T}: Add {C}.
{T}, Pay 1 life: Add one mana of any color. Activate only during an opponent's turn.

Once each turn, when you gain life, you may exile the top card of your library. You may play that card this turn.
Whenever you cast your second spell each turn, Ignition Engine deals 2 damage to target player or planeswalker.

Bloodprice {B}{B}{B}{B} (You may cast this card by sacrificing a creature and paying its bloodprice.)

Sacrifice another Demon: Jejun, Dark Hunter gains flying and indestructible until end of turn.

Indestructible
As long as your devotion to green and blue is less than seven, Kruphix isn't a creature.
Spells you cast from anywhere other than your hand cost {2} less to cast.
At the beginning of your upkeep, if there are no cards exiled with Kruphix, exile the top card of your library face down. You may look at and play that card for as long as it remains exiled.

As Nebula of Empty Gold enters the battlefield, choose two or more colors. You lose life equal to the number of colors chosen this way.
{T}: Add one mana of any of the chosen colors.

Once each turn, when another creature dies, you may crystallize. (Put a +1/+1 counter on a creature you control or create a Treasure.)
Whenever an artifact you control dies, Nihilistic Shock Trooper deals 1 damage to each opponent.

Other Merfolk you control get +1/+1.
When Olantin Pearlreader enters the battlefield, scry 2. Then draw a card if you control two or more other Merfolk.

Look at the top two cards of your library. Put one of them into your hand and the rest into your graveyard.
Rerun (If you cast this from your hand, exile it as it resolves. Whenever a creature you control dies, you may cast this card from exile without paying its mana cost.)

Choose one —
• Qi-Long Gust deals 3 damage to any target.
• You and permanents you control gain hexproof until end of turn.

Lifelink
Once each turn, when you draw a card, you may reveal it and a card you own from outside the game with a different name and the same mana cost. If you do, exile the first card and put the second into your hand. (Mana costs must be identical.)

Choose one or more —
• Counter target activated ability or triggered ability.
• Prevent all combat damage that would be dealt this turn.

(Transcend as a sorcery to gain that type and a +1/+1 counter.)
