Hmmm, this feels like it exists already. Though... I'm thinking of a card that only worked with artifacts, or phy? Something from around then.

Shouldn't this be uncommon? I'd say it's a build-around; but I guess it's actually just "Hurt the opponent, wait, why would I not do that anyway?"

It also clashes with magic unofficial terminology of 'ritual' being mana production. But that's minor.

And last comment - should probably be "another source deals..." because otherwise it powers itself and that's odd. Having four of these in play is also instant game over; which... maybe it's intentional? It's really cruel though.

thank you for the input. there will be a worship mechanic that works like ascend and historic.

if you control one ritual, one wonder and one god you get worshiped. this might be way to powerful.
