I play classic log bait in ladder, and there is a quest to play miner in ladder so I replaced the ice spirit with miner in the deck and play some ladder, it feels pretty good.
Goblin barrel/Goblin Gang/Knight/Princess/Miner/Inferno Tower/Log/Rocket
There was a 3M match up, I no longer need to rocket the pump or find some crazy high pressure combo, just miner it. The opponent mainly used goblin gang to stop barrel, so he did not have good ground distractions for the miner, he had to minionhorde/bats on it but it will still let the miner get a few hits, then the horde/bats will die to my princess. The 3M match up has never been so easy.
In other match ups it feels pretty much the same, may be slightly weaker than the classic because the cycle is sometimes awkward without the ice spirit.
With 3M pump being so popular, I think overall the switch to miner is quite solid.
What do you think?
