Myriad is a triggered keyword ability that creates token copies of a creature when it attacks
In many peoples eyes, this red creature invalidated creature-based decks, being able to pick off a full board relatively easily, while leaving behind a 3/3 double striker to quickly end the game with yourself
But be careful, in case the Tron player can play around that
This complicated baton-toss maneuver isnt terribly useful within a game of Magic , but in equipment-heavy voltron decks (where you focus on beefing up one or a few of your creatures), Cloud is totally viable
All of those cards are either iconic (such as Ravenous Rats and Coercion) or powerful, (such as Goblin Matron) or play very well, like Sylvan Basilisk which kills immediately upon being blocked, not when damage is dealt or at the end of combat - which makes it the best Basilisk ever printed
However, the salt factor for some cards is so great that even the most patient players cannot deny it
