Reverse
Instant
Return target spell an opponent controls to its owner's hand. The next spell you cast this turn costs less to cast, where X is that spell's mana value.

Reimagine
Sorcery
Discard any number of cards. For each card discarded this way, draw a card and put a +1/+1 counter on a creature you control.
"I don't like this ending. Draw a better card." — Commodore Guff

This one is difficult because there was copying spells/changing targets and that could be blue without white and there was a spell/storm-based buff spell and that could be white without blue.

Punish
Instant
Punish deals 3 damage to target creature or planeswalker that attacked, blocked, and/or was activated this turn. Tap that permanent and put a stun counter on it. As long as that permanent remains tapped, it loses all abilities.
"I will be blind to evil no more." — Kasla, the Broken Halo
