So I have a few reps under my belt now. My findings:
Basic island allows for a wasteland proof way to keep wonder online, this has been relevant a few times, and I expect it to be more relevant in paper given higher density if unpowered hate bears decks.
In my testing with gush it is either the perfect card or the worst card. Analysis is probably the better draw engine.
PO is playing repeal again, so I have shaved my third lavinia for a teeg. This also avoids some awkward double lavinia draws.
My current hate package in main is:
1 gaddoc teeg
1 containment priest
1 walking ballista (more there for the memnite trick)
2 deputy of detention
Deputy is great, but harder to cast, I am going to try a 1 deputy/1 manglehorn split. But it softens the mentor matchup.
My sideboard is currently:
3 Swords to Plowshares
2 energy Flux
2 nature's claim
2 containment priest
1 thorn of amethyst
2 ravenous trap
2 mindbreak trap
I think the lavinia I shaved should take the spot of the thorn. I am also considering moving the island to side.
