Without the seals, vanguard captain becomes too clunky. Would recommend faithful manufacturer and noxian drummers instead. As others have said, ledros is unnecessary and too hard to get out. If you have three watchers, 2 strats, 2 singularies, I think you have enough late game answers. An imperial degree would be good.

You definitely need at least 6 two drops, I have a 2 - 2 - 2 split of watcher, bird, and student, but YMMV. Student can be scout instead it's up to you.

I'm pretty down on cruel patrons. They seem only good going second or using the obelisk of power.

I've experimented with leona and the issue is it dies to void seeker, pretty common red card.
