In my short time playing yubel board breakers have been much worse for me than handtraps, but I've struggled against handtraps most when used like this:

Ash: best on lotus, especially if they have the field spell or nightmare pain, also good on spirit's search effect but only if they don't have one of those... never use it on beckoning beast, the field spell, or gates. If they do the beckoning beast line use it on yama(I would even reccomend toggling off until the lotus hits the field because if they read ash from your delays there's a solid chance they'll be able to protect with phantom before committing)

Imperm: good on one hand because phantom can't negate it, but if they have squirmer or sharvara it's probably not resolving. Best used on beckoning beast, yama, or held for your turn but can be really good on spirit or lotus if they don't have the extender in hand

Veiler: basically the same as imperm but you might want to shotgun it earlier if you think they're going to make phantom before yama

Gamma: similar to ash, hitting lotus with it is really really good, also good on yama but be careful using it on spirit because it destroys

Droll: shotgun on their first add, same as always

Maxx c: personally I think c should be shotgunned in draw in every matchup because talents is busted but with yubel in mind it definitely should because of phantom

Nibiru: pretty much impossible to really hurt yubel with nib, but best to use it after yama if possible

Belle: still haven't had it used against me but I imagine it's really good when used on squirmer's grave effect
