Rizen

Description
Whenever your opponent summons a minion, this minion summons an Egg of itself nearby.

Interactions

 * Even though Rizen spawns eggs there is no synergy in an Eggmar deck (a deck focused on Rebirth and Chrysalis Egg synergies) because the Rizen's eggs only spawn on the opponent's turn (except if you summon Komodo Hunter). Therefore it doesn't synergize with Morin-Khur, Lava Lance, Egg Morph, Wild Inceptor etc.
 * If you summon a minion whose Opening Gambit kills the Rizen, it will still spawn an egg. But it was also observed that a Frostbone Naga killed Rizen without Rizen summoning an egg. This needs to be looked at closer.
