xingshu essentially being a 8/ 8|9 life gapper on rounds 3 and 4 respectively and a 8/5 vs soa is quite possibly the most solid 4* worth splashing. With another skeelz member as the only 2 splash units, the main clan bonus is guaranteed. So... I went experimenting a bit this week~ I didn't get to play many games, but but results for the following clans were quite promising.
Tried a bunch of different variants with different clans, vortex seems to be the best home for this atm. The pill retrieval with the overall high life gaps pushed xingshu as a late game threat really well.
Frozen worked well since just about every unit unit poses as a decent threat.
Montana seemed to work fine as well cause fo the early game pill forcing, but lost out on late game bluff potential.
But that doesn't matter, the skeelz bonus does nothing most of the time. Hell I'd argue that its usually better to have a 3-1 with just xingshu or redra since you'll have 3 cards from your main clan to do what they're meant to do be it win or pill force, and then you'll have redra to dr/call bluffs or xingshu as a late game bomb. SoA clans don't hurt much cause of the high base stats and SoA units can be played around.
