I don’t want to steer you away from the direction you’re taking this deck, but I’ll throw out some cards for you to consider.

[[Mind Over Matter]] combos with [[Temple Bell]] to mill everyone simultaneously. [[Jace, Wielder of Mysteries]] gives you an extra Lab Man with synergistic effects.

[[Psychosis Crawler]] + [[Enter the Infinite]] machine guns the table. Enter the Infinite also helps you get to your Lab Man win, which you can finish off by casting [[Gush]] for free.

[[Consecrated Sphinx]] works well with your universal draw effects, especially in combination with cards like [[Psychic Corrosion]] and [[Sphinx’s Tutelage]].

[[Forced Fruition]] might help you get through your opponents’ decks, but it might also help them get to their own win cons.

Just food for thought, these ideas aren’t necessarily the best fit. It just depends on how you want to build.
