Hot Potato! sounds fun, and the previous ones could be interesting, too. Putricide sounded "meh" until I realized this also applies to Heroes, so it would be a counter to "Healers".
Putricide is broken, and way to easily exploitable. Imagine if Warlocks could have their health frozen at 10HP or so, or if freeze Mages and Druids could freeze your health at 20 or less HP. It would be absolutely game breaking, making it impossible for decks that do not have burst damage to be viable in comparison to decks with the Force of Nature/Savage roar combo, or 2x Frostbolt and 2x Icelance, for a whopping 14 damage each. In addition to that - Reno Jackson does not necessarily require a nerf as of this moment - He generally weakens a deck by requiring around x1 of each card, and generally, if the opponent has board control, Reno will generally delay defeat.
First Thoughts could be amazing if you get it and some combo spells in the starting hand.Otherwise it just seems to lose value in the late game.Really a card that requires vast experimentation, I hope Blizzard designs somthing similar to it.
First Thoughts is good if you find yourself running out of cards or, in fact, if that's the only card in hand. If, on the other hand, you drew a good opening hand with low mana cards and now have a good hand worth of mid to high mana cards, it would probably suck!I love the time bomb cards, that would be so much fun!Dark Flamer is 5 mana for 5 damage if you play it on the same turn, which doesn't sound worth it. If you hold off, however, and it survives, you could potentially get some value out of it before you hero power. Certainly an interesting one.Yo bot is a bit silly. Getting a golden hero is not going to be very impressive if your opponent sees you got it from a card. A 3/2 for 2 is fair stats but there are plenty of other cards with those stats and much more useful effects (admittedly, none of them are mechs).
First Thoughts seems broken, being an unlimited source of cards should you manage to get it in your starting hand. This kind of infinite loops isn't exactly how the game is meant to be, I wager.Putricide encourages aggressive burst decks even more, and, yeah... What's wrong with people? Look back, look at the ladder right now. Haven't we had enough? Pretty sure he could've never made it into a card, though.
Dark Iron Flamer looks the coolest out of this bunch and if 3/2 2mana minions weren't the normal right now it would be allot better.Also making your hero from a golden card is pretty funny
Another thought: Hot Potato is actually OP against Rogues because this will force them to discard weapons and the enchants.
