The problem is that they really don't need anythin'.

They have both OTK and turtle potential. Their one problem is consistency, which is mitigated by ROTA and their field spell. If I gave them more consistency then they lose one of their balancing factors.

Thy don't have a reliable way of boarding multiple monsters which could help them so originally I wanted a pair of themed Pendulums. But Pendulum summoning goes against the decks tag in/out theme which requires monsters in hand. Besides there's multiple Pendulum archetypes that can be splashed im with any deck so themed Pendulums would be redundant.

So a new UA would either do somethin that the archetype already does, or cover one of the archetype's weaknesses that balance the deck out in the larger meta game.

What I can do, however is make a semi-generic card that can act as an off-theme support.
