The phrase too-specific might sound like a backhanded insult, but putting down something early that synergizes with your gameplan and consistently refreshes your hand is going to provide you way more value over the course of the game than a simple mana rock ever will
May I suggest Goblin Cannon, Rocket Launcher, Fleetwheel Cruiser, Goblin Charbelcher, Jade Statue, Phyrexian Processor, Time Bomb, Wand of the Elements, or Whirling Catapult instead
Id rather pay a few extra mana to know for sure Im breaking up my opponents combo than cheap out and find my spell fizzled, wouldnt you
Excellent (EX): Cards graded at Excellent have minor wear, often from gentle play
This is how it ended up like this
