I'm assuming this was a hard counter to SEA and (mainly) Midseasons. Cheap to splash too, so I guess it might make a decent 1-of in SMC-reliant decks not wanting to use Plascrete. For 1 credit (instead of 3), you can avoid those two threats (and for 1 MU, unfortunately). Unlike Plascrete, its viable against any large trace.

Pros

• 2 credits cheaper than Plascrete
• Essentially negates Midseasons Replacement

Cons

• Consumes 1 MU
• 1 Influence outside of Anarch
