haha hrmmm, I did already remove the #.
I agree those problematic cards could be a problem, however I find the AI to be a bit flawed in how it plays many of them. This is, IMHO, the strategies for those cards (mainly for those that don't already know how to play)
Chimera, when used by AI5, doesn't usually produce a creature with enough attack to overcome my healing. [edit] didn't see your screens, clearly it CAN happen, but I would argue that maybe you should have cleaned house a bit before Chimera was used.
Earthquake/Quicksand, is OFTEN used too early by AI. My experience is that it will use it when only 2 towers/pends are played. And, so far, run into a max of 2 of these cards played against me.
Trident - I explode it!
Steals, usually used early by AI and with 2 of each weapon and shield, I haven't had issue yet. Usually I lose 1 weap or shield then a SoG. As soon as I see steal possible, I draw it out with SoG as those decks don't usually have high attack.
Mindgate - I explode it!
Silence - yes u can't play a card, but I've yet to have it cause a loss.
Discord - explode it, otherwise, not THAT big a problem.. Still produce plenty of Fire.
Unstoppable - only a problem on big creatures. Lance em.
Dragons - use your Lances as stalls IF you are getting low on HP until you get SoG and buckler out. Only use your Lances if one Lance gets you the kill. don't waste em.
Reflective - this is the FUNNIEST one... I actually found that nearly EVERY HB that had reflective would drop it for another shield (spiny, grav, etc...) late in the match! Perfect time for the lance attack. In either case, you should play to get the Fahrenheit win if you see reflective shield. Use the Lances for CC as needed.
Against human players these cards are much more of a problem as they would be used more appropriately.
Most important thing here is to adjust your gameplay based on the opponent. Also, you shouldn't sprint for the win, or else you'll miss more EMs. Don't lance creatures just cause you can, you only lance those that WILL and are ABOUT to cause you to lose.
Most of the time, I'm winning with most lances still in my hand.
