Tell me which champs always suck.

TF can be good in certain sorc/shapeshifter comps. It's kind of a dice roll, cos if you get blue cards, you are god that round.

Morde is certainly the weakest knight ingame right now.

Mordekaiser really needs to have 600 hp like the other level one knights, really don’t understand why he only gets 500 when Darius and Garen get 600.

Also TF isn’t bad persay, just getting the units to make him decent through sorcerer is hard. Also he is basically an adc and he needs items

Mord is just....a troll pick. He doesn't do anything better than others. As a tank he has no tanking ability nor sustain, as a bruiser he doesn't do more dmg than any other melee. He's really just there for knight trait assuming it's even worth it, and it's worth only if you somehow manage to get 6 noble 6 knight comp and swarm your enemies.

TF tho, he can make or break some comps, and early on as a cheap 2gold unit he makes it possible to rush pirate trait without relying on finding that 3gold gankplank. It's especially significant for those rushing on-hit gunslinger comps cuz u need to stay low level and spam rerolls to get those 1gold units to 3stars, making it impossible for u to bank and that's where the pirate's extra gold comes in handy for those extra rerolls.

Morde is there for an easy phantom bonus. I have won many games by having a 2 star morde and a kindred out there to get the phantom buff and simply erasing one of the enemies' best champions from the battle.
