What archetypes do you think I stand most chance to beat?

Hmm i'm not sure, i have no experience with stasis. But it seems my 2 legacy decks would have no difficulty dealing with yours. The problem is you need 3 specific cards to complete your lock, and that is fairly easy to disrupt.

I found this thread with someone who had some succes with a stasisdeck:

If you are playing this deck causally Gush . Gush is my favorite card on the legacy banned list, It gives the player a pretty great card advantage and you can tap the island before returning them to your hand, even still i don't think that's too overpowered. Blue is already insane though, this card would break the legacy format. I've had great success with my deck You're the Bitch, Bitch for about ten years now. I use merfolk to power Opposition and keep opponents tapped with Static Orb . I've updated this one quite a bit, the original had Merfolk of the Pearl Trident
