Glimmer is a dragon, flyer, and earthwalker, and is affected by cards that target those qualities. Glimmer may retrieve one magic item or artifact from the discard pile each time he is victorious in battle (this does not require spoils to be drawn. These items must be attached to Glimmer.) Artifacts must still be attached legally. The Ego Coin [2nd-419] is a good choice for Glimmer, to allow him to retrieve artifacts from any world and attachment, as well as the Wand of Orcus [4th-456], since Glimmer is AD&D and this would help him win the battle.
Another great combo for Glimmer is the Blamblower [DL-56]. At the start of battle, you blow up the Blamblower (discarding and defeating the opponent unless he started the battle with a +6 or greater ally in battle), then retrieve it with Glimmer's power. This would be especially nasty with Dragon Raid! [DR-20] in play. Since Glimmer's power activates after winning a battle, there must be a battle, i.e. if Glimmer is unopposed when he attacks, his power does not activate. Glimmer can be a good addition to a recycling theme deck. Other cards that have similar powers would be Halcyon [1st-c16] and Remnis [4th-481].
