The challenge with WU is that its often one of the slowest color pairs
It's very strong with going wide like Mono-Red Aggro, Mono-Red Tokens, or alongside those themes not just as a Commander like Boros Aggro or Tokens
So long as you're playing a Doctor Who-themed deck, your TARDIS will be waiting to cast free spells with every attack
That isnt to say this is a bad effect for mill decks itd find its best home in mono-blue ones that make drawing cards a priority
ASSEMBLING THE AUTOBOTS While each of these cards has its own subtleties and could be a worthwhile piece to slot into some existing deck, a lot of people will be trying to play as many as possible
However, it is important to recognise when an idea doesnt work as some ideas, while sounding cool, just arent fun to play in the end
