The Transformers TCG continues to hang around however we don't expect the game to stand the test of time. Wizards continues to release new sets and the newest one is Rise of the Combiners.
Information from the Sales Sheet:
"Transformers TCG: Rise of the Combiners features the debut of combiners - character cards that combine to create a single giant robot! There are six combiner groups in this expansion, including Predaking! Characters combine using new "Enigma" cards and by having all parts of the combiner in bot mode on the battlefield or in the KO area. Each section of the combiner may have an upgrade and all damage from each section carries over to the new combiner bot."
