Noctis, Prince of Lucis + Aetherflux Reservoir + Solemnity + Welding Jar

Noctis, Prince of Lucis

Aetherflux Reservoir

Solemnity

Welding Jar

How it works

1. Cast Welding Jar from your graveyard by paying 0 and 3 life. It will not enter with a finality counter due to Solemnity.
2. Aetherflux Reservoir triggers, causing you to gain 1 life for each spell you've cast this turn.
3. Resolve Welding Jar, and it will not enter with a finality counter due to Solemnity.
4. Activate Welding Jar by sacrificing it.
5. Repeat
