R5 science gem for Rulk?

Here are my top champs and all my 5* science champs..


I’m Cav barely, but have lots to do for Act 6. This would round out my top team with 5r5 Domino, Cap, Corvus and 6r2 Doom.
I also have multiple AGs available.

Use it on Rulk if you regularly use Domino.
Wait if none of those apply.
Wouldn't concentrate on Synergies so early.
