Unlike a traditional Clone effect, though, your opponents creature no longer has its abilities
The upside is that it's colorless, so you can run it in any deck, and it's also lacking any sort of restrictions, so you can search up any card at all from your sideboard
Stifle (2009) Stifle does what few other counterspells do, and it does it well
My biggest piece of advice is to guard yourself against overvaluing your cards and/or overvaluing a card youre interested in purchasing
Then amass Orcs X, where X is the number of instant and sorcery cards in that player's graveyard
If two or more effects attempt to modify how many counters would be put onto a permanent you control, you choose the order to apply those effects, no matter who controls the sources of those effects
