They desperately need to print straight Draw 4 supporter card. Would be good and balanced.
Yes and no. I realize it is unlikely, but
just maybe "Draw 3" Supporters will start working at least a little for competitive play post-rotation. Now,
retroactively, then I completely agree! Cheren and Tierno were part of card pools containing N and either Professor Juniper or Professor Sycamore or both. Up against
that, "Draw 4 cards." is balanced.
The thing is, I think Professor Kukui, and possibly even the new Tate & Liza card show the best approach... even if we've had a few more duds than successes. What I mean is, instead of drawing more cards, you add a worthwhile bonus effect. Yeah, Pokémon Breeder didn't do it all that well, but I blame that on them forgetting that offense > defense, so it really needed to heal more. Lillie half-pulls it off as well, with her drawing extra on your first turn.
I'll resist making suggestions for how Samson Oak
might have worked since this isn't a Create-a-Card thread.
