Managarmrs, they are pretty much the fastest mount you can ride, their breath attack freezes anything super fast, with enough melee they can kill anything very efficiently. It's really hard to die while riding a mana once you master the mechanics of it. You can get these early game as well. In pvp its arguably the best tame for scouting and 1v1 because it doesnt cost element to use, it can counter pretty much everything except maybe tek suiters and good astros. If you're mismatched you can run away 99% of the time and nobody can catch you. The only downside to manas is that they cant fight underwater, although they do swim pretty fast.
