My highest attack synergy

Kerem

Yelowjacket and Antman %6 Attack
Antman and Yellowjacket %6 Attack
Yellowjacket and Super. Iron man %4 health&attack
Beast and Super. Iron man %15 attack after 15 combos.
%16 attack, %4 health and plus %15 more points when you reached 15 or more combo.

I used 3* Super. Ironman, if anyone has 4 or 5* may have better result.

If anyone has better synergy for attack, please share with us.
(I specially use this for my 3* Hyperion, I don’t have 4 or 5*)

If you're doing all this for Hyperion, it may be worth dropping 2 of them to bring in a Cosmic Supremacy synergy.

Nope, not just for Hyperion. If it was I would share Cosmic Supremacy.
