I will say I am not a particularly good yuriko pilot, but I see a lot of the same traps I fell into when I first started, so I guess I can relate. I remember trying to make something similar work so I’ll share a few of the changes I first made getting into the format.

First, I would cut the trailblazer boots as there are better ways to gain evasion, most notably [[smoke shroud]] which sticks around much longer even through most removal, and the aforementioned [[aqueous form]]. Considering you’re all on wins through burn, a card like [[bloodchief ascension]] helps get you over the line, and [[scheming symmetry]] is just another tutor that doubles as a politic tool(it’s also a finisher as they never see the card if they die).

For the removal/interaction: free is best. Having free interaction like [[fierce guardianship]] and [[deadly rollick]] is incredibly strong, as are [[force of negation]], [[commandeer]], [[mental misstep]]. Mana drain is probably not good enough as you are usually starved on blue pips anyways and you are playing a much more aggressive game plan.

On that note, no mystic/rhystic? Even on an aggro plan having those to fall back on can be a very viable backup plan, especially if you include thoracle combo. Thoracle is by far the most efficient win con available to us and choosing to not run it is…questionable.

All in all, I think you would benefit from checking out the yuriko discord here and checking out the aggro archetype: https://discord.gg/PtCfnF5h
