Some people have said that Himiko is safer to play. However:

3:25 - Since this second and ownards, Castoria always has 500% Overcharge. So this version of the Team can also reach peak safety in the right conditions and if it's played properly.

Ah yes, my favorite word, "if". It's always " If", "if", and " If" 😂

But Himiko Punch!

Both options have advantages, Morgan helps with more stable team charge, Himiko means better crits. I'm happy with either. Himiko I prefer since I'm less likely to lose her if the shield drops, but against a Berserker, it makes no difference.

To be fair, both options are great. Himiko assures 500% overcharge always (not needing Castoria NP2). And if the shield happens to fail for whatever reason, Himiko's a ruler class (quite opposite to a Berserker Class).

I'm just remarking 500% Overcharge still possible with the Morgan version, something that not many people know. Harder, but possible.

I personally prefer the Morgan version simply cause she's my waifu. ❤️

Both of you saying "if" again, ha ha 😂😂.

I say if for when things go bad, such as a single servant getting target and losing all their shields before the other two. Which does happen.

I mean, there's always gonna be an "if", because luckily, there's no single strategy that's "the very best" and 100% effective for every single situation, even ignoring luck factor. Otherwise, the game would be too boring to be honest.

This stall team is almost unbleatable, "if the enemy doesn't have debuff removal", in which case you would need to try the variations with Arcueid or Beni Enma.

Or either min-turn and use supports as Santa Nightingale and Xu Fu to protect only your DPS.
