One team I've grown particularly fond of came from another player on these forums and led to me testing it out. It works great in pvp and non-goon pve. (3/5/5) (3/5/5) (3/5/5)
Variation 2 is for goon nodes: 5/3/5
Same basic strategy as above, it leaves more vulnerable but the damage that does every time a goon fires off a power is worth it. I prioritize blue a little more with this set up as his stun is so good. added strike tiles can almost double damage.
The Strange variation gets me through TBE with practically no damage to the team
I will archive my long-run 3* team for TBE here.
The team: IM40(x/x/5) + 3Torch(5/3/5) + Groot(5/3/5)
How to play: The general idea is to multiple-dip Groot's strike tiles with 3Torch. Chase 6 yellow ap for recharge as usual. Drop groot's massive strikes tiles. Drop 3Torch's green when you have 'enough green ap' (I usually drop the first one whenever the recharge tiles go off. I add the second when I have ~15 ap and 3rd at around 20.) Drop 3Torch's black if you want, but totally optional. Save up red ap for nuking any tile-movers if ones show up. The fun part is there are several times when I have 3x 3Torch's green tiles on the board and manage to drop 2x Groot's blue. The result is I one-shot the next wave during my upkeep (the time between the start of you turn and when you can actually move the tiles.)
Why do I archive this team ? Honestly, I am bored with this team and looking for a new team to try out.
PS: This team works okay-ish (up to R5-6, maybe) in any boss fight as well.
