Holy Water, Accusation, Begone! and Bind Evil all get turned on by Persecutor's second ability, giving quality removal and banishing whatever card from hand you want can be backbreaking.

Self-mill via the lands helps for early Colossus and Redmane, or digging for a good Corpse Explosion finisher.

Pretty sure Silent Hills turns off card text boxes and Genesis, which alleviates the life loss of Lesser/Greater Blood Demon and Corrupter Freak.

Tech cards:

Inquisition - Accusation/Lookout counter

Sir Morien - blocks enemy projectiles, allows your own to pass through

Cherubim/Talamh Dreig - sticky, hard to remove top end. Cherubim has a built in 4-damage projectile (kills an Ironclad on DD) while Dreig requires a kill spell.

Betrayal - better Infiltrate, doesn't get countered by Watchtower

Hellfire - anti-burrow/submerge and anti-skelly token card

Toolbox Wishboard:

3x Dispel - Enchantress/artifact hate. I'd consider main boarding one, but unless Feast for Crows naming Toolbox becomes meta, I'd rather have more gas.

2x Smite - can be a strike or banish, seems good to be able to call if needed.

Spin Attack - testing for a cheap tutorable site clear; on my "maybe cut" list

Minor Explosion/Heat Ray - two different finishers, one for Ironclad and one for everyone else. Depends how much that null-2 matters. Probably only need one.

Critical Strike - pet card, testing to see if it's worth the slot. Ceiling: unblocked Colossus, doming enemy avatar from 20 to door in one hit. Floor: wasted collection slot. Ceiling is probably never going to happen, so trying to find the average use-case and see if something else can be used better/more frequently.

Rescue - another pet card, testing. I don't think there's enough positive EtB effects for it to be worth it, but recycling the top end might be enough.

Manabase:

Work in Progress. Decently satisfied with this iteration, needs testing to improve.
