Rath is the highest source of damage in the Skyspear Avians' faction. With 4 melee strength and the ability to teleport (though no Flight ability), Rath can hit hard and practically anywhere. Unlike Gilford, Rath doesn’t need an army. Rath is the army. Prey is very versatile and allows you to attack cards that are hard to reach. Don’t miss however the "secretly" more powerful part of the ability, which is to strike and hide, an important strategy because Rath's life is quite low for its cost.
Rath is more suitable for a slow game and the fact that it costs 6 magic adds to that, but if allowed to roam freely, this champion can take over the game on its own.
