More often than not though, a blue filter effect will have the draw be equal to or larger than the discard
I give it specific guidance, like Rate the power level of the card on a scale from 0-6, where 0 is unplayable, 1 is very weak, like a bad common, 5 is very strong, like a bomb rare, and 6 is super overpowered like a black lotus
You can soft-lock players with cards like Meren of Clan Nel Toth, Abiding Grace, and Tortured Existence to prevent anybody else from having a meaningful combat step
