Serve, Protect, and Slice

This deck has all the toughs. You have Colossus, Armor and Polaris. Additionally, you can add toughs and flip down without trouble using Serve and Protect which will also add another 2 toughs. X-Force Recruit can help make this a possibility (via extra X-Man ally), but could be used on yourself in a pinch. You'll generally use Protective Training on Honey Bader (for your readies), Rogue (powerful activations + X-23 readies), and Colossus (Rogue may sometimes want 5 attack instead of 3). Game Time will ideally be used on Honey Badger, but Rogue can be a solid choice if you need massive thwarting. Since you could be flipping a lot, Moira comes in handy.
