Veil of Summer

Choose one. If you control a commander as you cast this spell, you may choose both instead. • Creatures you control gain flying, vigilance, and double strike until end of turn. • Creatures you control gain lifelink, indestructible, and protection from each color until end of turn.

Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.) You can't lose the game this turn and your opponents can't win the game this turn. Until end of turn, damage that would reduce your life total to less than 1 reduces it to 1 instead.

Destroy all lands.

As an additional cost to cast this spell, sacrifice a creature. Creatures you control gain indestructible until end of turn. Put a +1/+1 counter on each creature you control. (Damage and effects that say "destroy" don't destroy those creatures.)

Return target creature card with mana value 3 or less from your graveyard to the battlefield tapped.

Create three 1/1 white Rabbit creature tokens.

Converge — Exile target nonland permanent if its mana value is less than or equal to the number of colors of mana spent to cast this spell.
