For example, if one of the exiled cards is a land card, you may play it only during your main phase while the stack is empty and only if you have an available land play remaining.
For the former, you can use Coastal Piracy to have tokens available for defence after each unblocked attack, any card drawn can be combined with Mystic Redaction, Sphinxs Tutelage or Psychic Corrosion, the Mystical Tutor and Solve the Equation help us find the right cards for any strategy, for example Time Warp, Pyromancers Goggles or Swarm Intelligence (matching the Commander)
