Summary: Who said you can’t summon URs off the Mimics? Here is Asahara’s Double Egg Combo.
How does this Unit work?
In comparison to Cubics, Mimics are great in sense that with its baseline 2 health, summoning Mimics on the its corresponding elemental field would put it higher chance of its survival during your opponent’s next turn i.e. increased chance of you summoning a creature with cheaper mana cost. The biggest drawback is unlike Cubics, you cannot summon UltraRares off the Mimics.
So this unit/combo works in the following way. You first summon mimic. Most likely you have the mimic survive until your next turn. So on the following turn of yours, you summon Cubic off the Mimic, then subsequently summon a Ultrarare in the same turn off the Cubic.
Comment: I believe this combo demonstrate great game balance back in the EOJ. Introduction of Mimic certainly did not placed its older brother Cubic into obsolete archeic creature, but rather each has its own pros and cons. Especially, interesting thing here is that you can combo two and get the best of the both. Clearly, the biggest drawback in this combo is that you are essentially using two cards for one creature, but saving 3 or more mana? I believe it’s worth it. The key here might be perhaps add a way to draw cards in your deck, so before or after carrying this combo, you still have sufficient number of cards in your hand. Though this would be a little bit less issue with Jade Mimic or Ochre Mimic as they both allow you to summon creature back from graveyard i.e. no reduction in cards from your hand except for the Ultrarare itself.
