Other creatures you control have haste.
Whenever Breach Titan enters the battlefield or attacks, abound. (To abound, you may cast a spell that costs less than this from your hand without paying its mana cost.)
At the beginning of your end step, return another target creature you control to its owner's hand.

Whenever a land enters the battlefield under your control, choose one. If it doesn't share a name with another land you control, instead choose both—
• Create a 1/1 Scout creature token that's all colors.
• Put a +1/+1 counter on a creature you control.

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

Draw a card, then discard a card. Mizuki gains “Noncreature spells you cast cost {1} less.”
{6}{U}{U}: Avatar
Draw two cards. Mizuki gains “Whenever Mizuki attacks, you may cast a noncreature spell from your hand without paying its mana cost.”

When Shadowbinder Touka enters the battlefield or attacks, exile up to one target creature card from a graveyard.
You may play creature cards exiled with Touka.
Sacrifice another creature: Add two mana in any combination of colors. You can't spend this mana to cast spells from your hand. If this mana is spent to cast a creature spell, that creature enters the battlefield with a finality counter on it.

Whenever you cast a noncreature spell, choose up to one target creature. If that spell's mana value is greater than that creature's power, put +1/+1 counters on it equal to the difference.
