Good Tanker units?

[Lysander]

Still early in the game, but I've discovered two units that tie up the other side while my distance fighters (mages, archers, etc.) pick them off bit by bit. Both Lina's ice orb and the phoenix (cast as spell) have plenty of hit points, so I place them in the middle of the enemy troops and watch while their units keep busy fighting the orb and the phoenix. The phoenix doesn't have a powerful attack, but she's versatile (can move anywhere) and has plenty of hit points.
