Change Letho/Regis (or add counterplay)
Letho/Regis wipes the floor with some decks (Axemen, NG Handbuff, NG soldiers, Moonlight, probably several more decks I'm not thinking of). The combo is so devastating that it can be worth >80 points. This is counterbalanced by the fact that both cards need to be drawn to be effective, and there are decks that the combo is ineffective against; however if the opponent has the combo these decks simply fold. There's no point even playing! They can't play around it, because their deck is built to make big units, and there are only three rows to split up on. They can't add any hate cards, since there are none. The best they can do is get the last play - nontrivial - and then kill Regis after it's been played, but even then the combo has still probably generated 40+ points.
I think there're two options:
1) Tone down the combo a little against the decks most vulnerable to it, buff it against decks that are not so vulnerable. For example, Letho could drain two units by half, but if none of these two units are boosted, fully drain up to three units instead.
2) Add hate cards. The problem is, I genuinely do not how to make one. Letho comes in, drains two units, he's now 40+ strength - but although there're cards that can kill a 40+ strength unit, that's your own 40+ strength unit you're killing. The only real way would be to spread the points out again, and I don't see how to make such a card that is still at least decently effective against decks not using the combo (without this, it's not a good hate card and probably people would just attempt to fade the combo instead).
Personally I prefer #1.
