{1}{W}{U}: Process
Precognition Module gains “Whenever you cast another spell with flash or an instant, surveil 2.”

Once each turn, when one or more artifacts you control deals damage to an opponent, you may exile the top card of your library. You may play that card this turn. The same is true for enchantments, planeswalkers, instant spells, and sorcery spells.

{1}{R}{G}: Pyresong Aspirant deals 1 damage to target creature. You may have that creature gain hexproof until end of turn.

Menace
Discard a card: Target artifact creature you control salvages Rappel Liner. Activate only if Rappel Liner is in your graveyard and only as a sorcery.
