Ayara, First of LocthwainAyara, First of Locthwain is also a standout here, letting you drain and draw cards all in one neat little bundle
I cant get into a full deck tech here, but there are some other cool interactions in this deck
"CMC=3 Power=3 -Color=Green" will return creatures that have a converted mana cost and power equal to three, but will exclude any green cards
Besides Rhystic Study and Mystic Remora, we have Candlekeep Sage and Teferis Ageless Insight, which both act as ways to reduce the time Cosima is in exile effectively turning her card draw up a notch and letting you send her away more often
Training: Become stronger by seeking out a challengewhenever a creature with Training attacks a more powerful creature, their own power and toughness will grow with a +1/+1 counter
While Aeve does stubbornly remain in the list as a pet card, however, filling the decklist with Oozes turned out not not actually be that great an idea
