This isn't just a coincidence either, as power seven or greater is a rather uncommon stipulation for Magic cards
For example, you could drop a one-turn or two-turn creature that can accelerate your mana, such as Wall of Roots or Llanowar Elves
Of course, you could always buy the single card, but given that its the most valuable Magic: The Gathering card on TCGplayer right now, youll need to have quite a few dollars to hand, to say the least
The level two ability, which costs two mana, returns up to two artifacts from your graveyard to your hand
Its channel ability lets you return nonlegendary cards to your hand at the right moment, making it a reliable source of card advantage
That means you can throw in a couple of big old cards into the mix, Commander is where those seven-mana do-nothing enchantment cards that get printed come into their own
