Undershooting (deliberately choosing suboptimal hands to play more total hands in a blind) has many uses, and has had them even before the beta branch changes. Scaling jokers, econ jokers, or simply gold seal/lucky triggers may be reasons why you want to undershoot.
However, the difference is that most situations that benefit from undershooting before the patch punished you very mildly if you got it wrong. If you accidentally won the blind when trying to undershoot, in most cases you only lost a tiny bit of growth or econ, with little consequence.
However, rental jokers change this equation significantly. I think that, as they experiment with the patch, strong players will quickly realize that it's nearly universally optimal to buy rentals if:
- You have the spare space.
- You can benefit from them somehow during next blind.
- You can sell them during next blind, before winning.
Basic examples are mail-in rebate, to-do list or rough gem. If they're offered as rentals, they'll cost 1 to buy and return 1 when sold, so they're literally 100% upside if you manage to sell them before winning the next blind. However, the penalty for getting this wrong (3 dollars) can be huge early, potentially run-ending in ante 1.
I think this design space (rentals having an upside) is good. I also think that strong players tend to have good estimation skills and are less likely to be caught by surprise by a winning hand. However, I'm also fairly sure that no strong player enjoys having a calculator out and precalculating every hand to make sure it undershoots.
