MTG Salvation

Whir is a terrible matchup. I have a couple Rampage of the Clans, but I don't know if that's right.

I think the Chalice + Infect aspect is hard to ignore. Also, the lack of W.

Blink is DEFINITELY a weak card. It's only real advantage is a good place to stash counters against removal.
Consider Animation Module instead of the Constructs. It solves that "I drew an Arcbound, what do I do with 3 mana?" issue that Affinity has once it's hand is empty.

Against Mardu. I've specifically played to maximize Module tokens. I think that's the strategy. Just keep pumping out bodies and pump them as you can. Synergies PERFECTLY with an Inkmoth when you drop Ravager.

In grindy matchups, Animation + Ravager is an "I win" button. Or Overseer.

I'm definitely feeling like Geth is the weakest card in his list. But maybe I'm not using it right. It seems to want 3+ things sticking around, and that can be tricky with all the spot removal. Animation seems better

I tried Spellskite, but it was NEVER a card I wanted to see over another 2 drop.

What about Animation Module or Shapers' Sanctuary? Sanctuary REALLY punishes spot removal, and Animation makes you go wide instantly letting you grind out things like Mardu Pyro.
