old gastly pokemon card - (47/108) defender is now Asleep Gastly #92 Prices | Pokemon

Teferis Moat is one such example where the reference is quite clear, although it puts a different spin on things by caring about the color of creatures that want to attack you

It's a relatively cheap price to pay for how much it accomplishes

For example, if you control both Loot and Exploration (an enchantment with "You may play an additional land on each of your turns"), you'll be able to play three lands during each of your turns

Still, you can theoretically build an aggressive ascend deck in Historic

So unless you are very patient and want to use a Switch trainer card, I would not recommend using this card in a deck
