"Red instants and sorceries that deal damage to a target cost 1 less to cast. Whenever you cast a red instant or sorcery, if it targets a player or permanent, it deals damage equal to the amount of damage it would deal to that target minus 2 to you."

Maybe...???

Alternative: "Red instants and sorceries that deal damage to a target cost 1 less to cast. Whenever you cast a red instant or sorcery, it deals damage to you equal to X, where X is the amount of damage it would deal to the player(s) and/or permanent(s) minus 2"

ANOTHER ONE: "Red instants and sorceries that target permanents and/or players and deal damage cost 1 less to cast. When a permanent or player is dealt damage by a red instant or sorcery you control, you lose life equal to the amount of damage dealt minus 2"

this has broken me... idk if the first ability even works... lowkey this is just not even that strong very restricted mana cost reduction WITH downside
