I don't see how Rock Bunker is easier.

I mean yea you only need to call Rock Bunker to get that 1 gauge but two conditions make it worse. One you have to have a Fist equip, specifically a Fist item which means your forced to use only those kind of Items and not everyone likes Fists. Sesters just needs an Item doesn't matter what kind.

And Two is that it only activates when he enters and that's it. What? Your going to just recall another one by retiring this one, or just hope your opponent decides to get rid of it somehow. With Sesters he gives you the gauge when he deals damage, yea it's a bit "harder" to do cause you opponent can block but it gives you more gauge over time without having to switch him out and waste cards as such.

Sesters is clearly the better Crimson Fist especially for 4000 Festival decks, but to each their own and Fist users will of course prefer Rock Bunker regardless anyways :P
