From Gamma Red.

IDK. I just don't see a justification in repeating a mistake done for Alpha that wasn't in GAMMA yet by reducing the casting cost of this card.

I see you went with the nerfed wording that doesn't cause the opponent to "lose next turn".

I don't think the mana cost is reduced here tho it's a bit hard to tell.

Some of the gamma renders have a differing costing syntax where 2R would mean "two mana of which one is red". So for example 6GG Craw Wurm, 5UU Air Elemental, 2B Bad Moon, and 3WW Reverse Damage.
