Title or sacrifice to a +atk -def Zelgius who has Armor March and planning on giving Bold fight to; or Fallen M!Grima who is -spd +def who runs vengeful fighter and ignis? Might make armor emblem team for Tier 20 arena but rn im keep falling into 19 every other season. I also have an Extra Kelin and 20k feathers if I just wanted to give B!Ike QR3
If it is your only B!Ike I wouldn't fodder him away, you got pretty much optimal IVs on him and if you don't have a high merged Zelgius I think it isn't worth it. Either wait for an extra B!Ike, or a few extra copies for Zelgius so he can become your main unit for arena.
