Hypnotize and Improvize are two actions that replace themselves, while Strike a Good Match, Tinker Bell, Pongo, and Lucky all give you card draw while also allowing you to filter your deck and select the optimum card for each situation
That said, Wizards has long had plenty of chase cards in Collector Booster packs
In addition, players can anticipate new gameplay mechanics with an evolved story with gorgeous art all of which is infused with electric energy that amplifies both the celebration and the gameplay
Thats not to say there arent plenty that had to be left out, because there were a ton, but these cards find themselves among the best
Im more often going to push this effect into my manabase, though, and just play the MDFC Song-Mad Treachery instead
Indestructible permanents is also about as good as it gets in this archetype, not that Knight-Errant needs her ultimate to be strong
