Awesome!!!! Now time to go wacky and have some fun.
Tip for anyone trying for infinite:
learn to retreat.
Simple as that, got yourself a deck that can compete? Awesome, now turn after turn, read your odds of winning with what you are drawing, if the opponent snaps, read his table and try to imagine what he have.
NEVER snap on turn 6 (odds of the opponent leaving is very high, win 2 cubes is better than 1). Exception to this is against Galactus and you have counters to Death/Knull.
Almost ALWAYS retreat if opponent snaps on turn 6, odds of he having the proper combo/cards to win are very high, exception is if you are damn sure your hand/last turn play is a huge one.
If the opponent is playing Galactus, and snapped earlier (before a Wave is the most common example here), if you don't have counters, retreat even losing 2 cubes.
Snap early if you have the base to your win conditions. Example, Sera control with Mysterio, Hit-monkey and Sera on hand, odds of you getting the missing pieces for that explosive last turn are very high.
Retreat to lose 1 or 2 cubes is crucial to climb to infinite.
After you learn to retreat, you will definitely know when to snap, it's a consequence of reading and understanding the game/decks of your opponent.
If you are playing HE and on the last turn you have Doctor Doom and Hulk, read the table.
Sometimes all we need is a Hulk.
Cheers and happy snapping everyone.
