If you think Fur Hires are TIER 0, well... I think you might be stucked in this rank down below. No offense ok?
Fur hires are easily counterable, you just need to negate their first summon effect and or play with monsters inmune to other cards' effects just as Hazys.
Btw? why do you hate them anyway? the little cats are very FUN to play !, and don't you say it's a dumb deck because YOU are the ones who can't beat them XD!, and I even defeated them with a ENDLESS TRAP HELL deck lol, so no big deal at all.
tried getting kog with heroes, amazoness and spellbooks and nothing worked. 5 wins in a row with heroes couldn't happen cuz with no restart the deck does brick every once in a while. spellbooks simply auto-lost every time furries went first. and amazoness felt dull every time i didn't draw princess. fur hire rearely bricked and was by far the best and most consistent out of all those decks so ...
The only Tier 0 deck in duel links, is cyber angel (before nerf) that was pretty nasty and very easy to use, no need to mention that the deck at that time is almost ftp.
IT'S BROKEN. You're lying if you say otherwise.
Trunade 2nd turn OTK, what can stop that? TRUNADE/CYCLONE makes them almost unbeatable.
As a silent spellbook KOG player myself, I can beat them easy if I go first turn, but they can still beat me at my best hand if they just have trunade/cyclone.
Their 2nd turn trunade OTK just doesn't give any sort of chance, unlike the other tier1 tier 2 decks.
