One of my joys in Magic the past year years has been the design and execution of a cube made up only of Uncommon cards
Common blue spells to play are Ponder, Preordain, Brainstorm, and Counterspell, not to mention power cards like Ancestral Recall and Time Walk
Both consistent and burst card draw are useful in their own right
The creators have also maintained that Lorcanas mechanics and gameplay will both draw in those new to trading card games while also giving veteran cardboard collectors new and satisfying strategies to chew on.
Unlike Cockatrice , MTGO provides gameplay automation , meaning instead of arguing with your opponents, you can blame the computer for everything (and you will)
It helps you find more fuel and punishment while raining damage on your opponents
