The original Archenemy set captured this nicely: Whether your planeswalker is an old friend, a new ally, or just someone who owes you a favor, they can come to your aid in your battle, and they are willing to cast their spells at your direction to help you defeat your adversary
And when youre looking for A) big fliers that, B) have attack triggers, you get your pick of some of the best and flashiest cards to slap onto the table
Put the chosen cards into your graveyard and the rest onto the battlefield tapped, then shuffle
A PSA Gem Mint 10 card must be free of staining of any kind, but an allowance may be made for a slight printing imperfection, if it doesnt impair the overall appeal of the card
If you can get this card and your board rolling, it becomes quite hard to stop
