Is it me or that is a very agressive sideboard card for Vintage? Against a lot of decks, it would create easily 9 power at instant speed. One green also means it's very splashable in artifact mirror matchups.

Instant speed means you can just play a more control game and slam this EOT or whenever you find an opening.

4 mana is a lot, but the effect is splashy. Interesting.

Would be funny to cast vs your opponent's full artifact board - and then they PO and draw 8 and you get 0 beasts

@thewhitedragon69 If they PO for 8, I don't think having 8 creatures will save you
