Octavia, Living Thesis will finish the game with unblockable creatures that hit hard as 8/8 beaters
Silvergill Douser is a Merfolk that reduces the power of a creature based on the amount of Faeries you control
And since you are playing an artifact creature to drop this, you'll always have other targets
For example, if youre on the play and your starting hand after a mulligan contains a one-drop, two two-drops, two four-drops and two five-drops, then I will usually start on turn one by inking the worst four-drop
I also think Aziza is a fun place for a small energy subtheme if you want to lean into some of the newer red-white token support, since the deck is already interested in building up extra resources over time before cashing them in for a huge turn
They hold up to 30 minutes of shuffling without a problem, and pretty much every sleeve still looks brand new
