Sentinel: Omega:

Sentinel takes two less damage from characters with the X-Men affiliation that it is engaged with.

How this card works: Sentinel needs to block or be blocked by one or more X-Men characters to trigger his ability. The damage reduction will reduce any damage from those characters, even if it is non-combat damage. The two damage reduction is once per character per instance of damage. That means that none of the X-Men engaged with Sentinel can damage it at all without dealing three or more damage at once.

How to maximize this card: Play against X-Men. Sentinel: Omega is a straightforward card. He has the stats of a battering ram and an ability to back it up. You should be attacking with him every single turn. He can be blocked by any number of Beasts and can go head to head with Colossus. You’ll need to do more than KO characters to win though. Thrown Car can help send Sentinel’s high attack values through to your opponent. Thinning the board with Hulk: Green Goliath or Toad: Tongue Lashing plus some activations of the Relentless Global might do the trick as well.
