Well, it should be clear that this card would only be regularly useful in a Greyhawk world deck. In combat in anything not a Greyhawk realm (including Dungeons or cards that cause combat outside the formation), Jallazari has no special power, being a random 8th level wizard.
When attacking a Greyhawk realm, she can get any Greyhawk champion in play as her ally that returns after combat unless discarded from battle. This can be useful, as there are many Greyhawk champions that see regular play, but it still requires that your opponent puts a Greyhawk realm available to you (unless you are using UnderOerth (8/UD)).
When defending a Greyhawk realm, she shines, being able to use a Greyhawk champion as an ally and return after losing battle against the attacker. However, there many champions with similar powers, and many magic items that grant similar powers (like the Ring of Regeneration (58/RL)) with fewer limitations.
Overall, unless you are playing a Greyhawk world deck, and need another spellcaster, I would avoid using this card.
