Either spread out cards like cosmo, colossus, antman and cap, to buff with spectrum or concentrate into a few lanes with warpath, mister fantastic and Klaw to finish it off with onslaught.
Omega can be swapped out for Namor if preferred/don't have omega.
Remember to be careful with Ebony and Cosmo if playing spectrum.
Foreplanning during the match may be necessary in order to avoid having resources stretched too thin.
Enchantress is the biggest threat here, with this deck only meant to work at lower tiers. Cosmo can protect against them.
