Good advice. I'll keep it in mind.
On a side note, this boss is broken as hell. You can only damage him by eliminating strike tiles? But he's not guaranteed to produce them, and it doesn't count as damage if he matches them, which he did non stop in my attempts. I've even used caps shield to try and get rid of strike tiles and it still does nothing.
What were they thinking? One Command point and 200 level points for this?
Hording tokens is really only important if your HP/roster slows are low and/or you're looking toward 4* land IMO.
The boss was fun but challenging. You can use someone like Patch, Elektra, Ms Marvel to give the enemy strike tiles to match away. It has to be a match, can't be removed by cap shield, etc. Quicksilver's black was my preferred method of popping stuff.
Deny black (to avoid his AoE). I would also suggest denying purple until you build up a black stockpile so you can deal with the strike tiles... you don't want them getting out of hand. If a strike tile is 2 matches away from being matched... don't do it. Let the AI make the move that sets up the match (or again, use QS).
My winning team was Spiderman (purple shields + heal), Patch, and QS. I didn't stockpile well enough and ended up losing patch/spiderman. I finished the match with a teamup Captain america shield creating a 3 in a row red match with a stirke tile. Kamala would be my choice replacement over Spiderman, but I don't have her well covered.
You'll need a favorable board. If he gets too much purple to early, you won't be able to handle the boosted damage. 15 black is a death sentence basically. 3 spiderman shields negated his 'regular' damage more or less. Bad shakeup nearly ruined me though.
