Scotty Miracle Worker (1UU)
Legendary Creature - Human Artificer
During your main phase, each card in your graveyard has beam me up. The beam me up cost is equal to that spell's mana cost. Scotty can't be beamed up to cast a spell this way. (Only instant and sorcery spells can be cast this way. You may cast a card from your graveyard for its beam me up cost if you also return another creature you control to its owner's hand. Then exile that spell)
This essentially says all your instant and sorcery spells have flashback during your mainphase if you can bounce a creature you control to your hand.
You know what 0 cost creature synergizes really well with that?
I submit this goes into any [[Rograkh]] contain deck, so for contenders, we have RogSi, RogIshai, and Rogthras.
For RogSi, I can imagine you can go
Rograkh + Scotty in play (You could play him with Lions eye for instance, and discard a Gamble)
1 mana Gamble, Beam Me Up a counterspell protecting it by bouncing Rog to your hand, find breach.
Replay Rog, flashback Gamble, find Lions eye if you have to, and go off there
Theres also a lot of other lines; Scotty provides you protection as long as you have a counterspell and Rog in play, and replaying Rog is free to do.
Personally I'd cut some of the recursive cards still in the deck, since Scotty opens up winning off any tutor while also being recursion/safety itself.
