The only drawback is that it wont last for long at the early game, but it is a huge card at mid late games, and at turn 3 or 4 it can slow down an aggro deck
Likewise, Ive been punished many times by needing white mana and only having a Scalding Tarn, Misty Rainforest, or Polluted Delta to go get it
There may also be extra transaction fees, depending on the payment processing service used by the buyer.
The most impactful that Id personally pick would be: Deflecting Swat, which is always good when you need to protect a Commander that attacks for value and damage
You instead cut out all of the cheaper dinosaurs and focus on ramping into Gishath and big monsters
It can protect our important cards from removal and is even better than a jar against cards like Maelstrom Pulse
