This is a 4-card combo and I'm curious if it would work out this way...
Covenant of Eden + Sucidical Swine Stampede + Legion (DI) + Tartaros
Covenant of Eden basically protects characters being removed from the game and instead discards them.
Sucidical Swine Stampede removes all of your blocking evil characters from the game to shuffle all your lost souls into your deck.
Legion makes Sucidical Swine Stampede cannot be negated and if He's captured he returns to territory instead as well as can band to another legion card as well as whenever Son of God is played legion gets discarded.
Tartaros basically places discarded demons onto tartaros and if a demon "wins" a battle, a demon placed on tartaros gets released to territory.
My question is, if a player uses Legion to block and plays Sucidical Swine Stampede with Covenant of Eden & Tartaros active, Legion would get discarded onto tartaros but although the Sucidical Swine Stampede would remove Legion from the game would that still be classified as a "win" for tartaros to activate that same turn and return Legion back into territory?
Pardon me on why I didn't quote from the reg, the online reg isn't working for me right now so I had to write based on memory.
