Gladitor cards are awesome. Bloodlust is an incredibly skill that allows them to become incredibly powerful and made even more so when combined with the enrage battle effect. Like this:
Which to show you how much he improved here's what his starting stats are.
Lets look at how this happened. First this load out takes a fair bit of mana. Between needing a 6 mana summoner, wanting the dry-bone Megaladone, and then decided to have the Night Reaper.
By the end of the first round I was kinda worried cause the Megladone was looking worse for wear. And the demoralize had Gorth's attack down to 4.
But then things get AWESOME. Gorth takes a little damage triggering ENRAGEEE and he finished off the shark so Gorth's damage goes from 4 to a massive 8.
Then his attack finishes off the flying squid bringing his attack up to 9.
Then the Disintegrator goes down, removing the -1, and giving Gorth another kill. His attack is now a ridculous 11, and his speed is an outstanding 8.
The deeplurker was finished off and now Gorth is up to 12, and is pretty much the Flash with a speed of 9.

And then the very last thing where the attack goes up to 14 with the supersonic speed of 11.
Watching this fight was so fun.
