Displacer Kitten + Throne of Eldraine + Haze of Rage

Displacer Kitten

Throne of Eldraine

Haze of Rage

How it works

1. If able, activate Throne of Eldraine's first ability by tapping it, adding that can only be spent to cast red monocolored spells.
2. Cast Haze of Rage with buyback by paying 3.
3. Displacer Kitten and Haze of Rage's storm ability trigger.
4. Resolve the Displacer Kitten trigger, blinking Throne of Eldraine. Choose "Red" as it enters the battlefield.
5. Resolve the Haze of Rage trigger, creating a copy of it for each spell you've cast before it this turn.
6. Resolve all Haze of Rages, giving creatures you control +1/+0 until end of turn for each Haze of Rage, and returning the original Haze of Rage to your hand.
7. Repeat.
