I cannot think of a way to bring zorga to Tier 1-2 level without fundamentally changing the way the deck works in the next wave of support
Orders are designed to fill a niche, so I can't see them creating something that powercreeps nectar or GDR for a kill turn. I also can't see them making a blanket guard restrict order without the risk of kneecapping all future support.
RG slots are tight, so it's hard to imagine a card that can fit into the deck as it is without disrupting the decks consistency or powercreeping existing cards.
The only thing I can think of is a card that allows you to use more than 2 orders or allows you to activate orders during the battle phase. Even then slots would be tight so who knows how impactful it would be.
Any thoughts?
