Engelbert is a the strongest physical tank in the game. He sludges through the map like a walking fortress. He smokes out squishies with the occasional Taunting blade and Saint cross. He has the most HP and defence in the game, and surprisingly, the second most luck stat.
He is a mainstay in Arena (although not as viable in match, suspect to kiting due to poor mobility). Slap on the "Vow of Love" vision card which generates hate and watch him sponge up all the physical damage. And if you have, pair him with the Esper Golem. Be weary of magic users, if possible avoid teams with magic emphasis as he is weak.
Best not to read the comments on these pages. Most people are ignorantly arrogant and will probably cause you to make mistakes if you trust their input.gist is, Engelbert is the toughest physical tank, but he needs help with magic defense and speed, or you should avoid magic teams. Paladin sub or knight is best, Paladin is my choice unless I need to break something. WoL is better in most opinions, because he does more damage and he's more versatile, but he's also limited. Hopefully this helps anyone who needs it, and saves them from scrolling down to the dregs of yhe final fantasy fan base.
