Whenever an opponent activates an ability of a permanent, if it isn't a mana ability, you gain 1 life and create a Gold token. (It's an artifact with “Sacrifice this artifact: Add one mana of any color.”)

Choose two —
• Target player creates a 1/1 blue Wizard creature token with prowess.
• Target player draws two cards, then discards two cards.
• Tap up to two target creatures.
• Target creature or player gains hexproof until end of turn.

Equipped creature gets +2/+1 and has flying.
Equip Wizard or Shaman {2}
Equip {4}

Whenever a creature dies, scry 1 and each opponent loses 1 life.

Activated abilities of nonland permanents cost {2} more to activate.

Magma Bolt deals 2 damage to any target. If a creature dealt damage this way would die this turn, exile it instead.

Harness (You may tap a creature you control as you cast this spell. If you do, reduce this spell's mana cost by that creature's power.)
Magnitude deals X damage to each player and each creature without flying that didn't harness it.

Lifelink
{3}{W}: Mahara Enforcer gets +3/+3 until end of turn. Activate only once each turn and only if you control another Angel or Nephilim.

Flash (You may cast this spell any time you could cast an instant.)
When Majestic Hippocamp enters, target creature gets -2/-0 until end of turn.

(Choose only one work as a sorcery to add its abilities.)
When Make Art Not Friends enters, create a Treasure token.
{1}{R}: Never Again
Whenever you sacrifice an artifact, that artifact deals 1 damage to each opponent.
{4}{R}{R}: Over It All
At the beginning of combat on your turn, you may have an artifact you control become a 6/6 Golem artifact creature until end of turn.

Enchant creature
When Make Way enters, draw a card.
Enchanted creature can't block.

Target player discards two cards unless they discard a noncreature, nonland card.

You gain 4 life.
Recruit. (Create a 0/0 white Soldier Army creature token, then put a +1/+1 counter on each Army you control.)

Remove all counters from target permanent with counters. If it's a creature or enchantment, destroy it.

Enchant creature
Enchanted creature gets +2/+0.
When Malignance is put into a graveyard from the battlefield, return Malignance to its owner's hand.
Lifecycle {3} ({3}, Discard this card: Create two tapped 1/1 colorless Elemental creature tokens.)

Enchant creature
Enchanted creature gets -3/-3.

Choose one —
• Counter target spell unless its controller pays {2}.
• Change the target of target spell with a single target unless that spell's controller pays {2}.

When Mana Potion enters, scry 1, then draw a card.
{2}, {T}, Sacrifice Mana Potion: Add two mana of any one color.

{T}: Discard two cards. If you do, draw two cards.

Manifest a creature card at random from your graveyard. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

For each of up to X target creature cards in your graveyard, create a token that's a copy of it. Exile the tokens at the beginning of the end step.

First strike
Manifold Manipulator has lifelink as long as you control a white permanent. The same is true for flying and blue, menace and black, and trample and green.

Slipstream (This creature can't be blocked as long as only creatures with slipstream are attacking.)
Whenever Manipulator of Waves attacks, mill three cards. Then create a 0/0 blue Elemental Serpent creature token with “This creature gets +1/+1 for each five cards in your graveyard.”

Frenzy 1 (Whenever this creature attacks and isn't blocked, it gets +1/+0 until end of turn.)
