While Double Merlin is far past the point of being desirabe in FGO meta, Double Tiamat is actually a pretty viable strategy in long / multi waves battle
Pro:
– Her S3 is basically Merlin’s Garden of Avalon if used every 2 turns. While you can’t “stack” it like GoA, you also don’t have to sit through its animation every turn.
– Her S2 is an impressive crowd control tool, albeit unreliable at 60% chance to stun.
Cons:
– No hard survival skill.
– Alter Ego class, so you’ll struggle vs Knight enemies.
All in all, this is not exactly “Meta” or anything, but it’s a fun throwback to the era where Double Merlin was the best thing you could do in this game
