To explain this rollercoaster pricing, Burgeoning is simply a great MTG card
That 3rd toughness makes a pretty huge difference in making the cards baseline a lot less miserable A two mana 2/3 with defender isnt great, but in a defensive deck it isnt unplayable, but the ceiling on this card just isnt very high, and neither is the floor
It's also very cool to see the Dark Depths + Thespian's Stage combo in a Commander precon
If it's earlier in the game and you're really in need of more lands in play, you can channel Greater Tanuki to get a basic land card into play tapped
After all, not all legal decks are effective
Our deck can naturally fight through creature decks thanks to Engulf the Shore and Crush of Tentacles, but neither of these cards helps us stay alive against a Turn 4 Aetherworks Marvel, so having access to main-deck counters helps shore up what would otherwise be a bad matchup
