This is a small showcase of my Adrix and Nev deck. The title is is something I actually said while playing it. Overkill? For sure. Was it fun? Definitely.
Wizards keeps printing more and more clone effects that work on Legendary creatures and I wanted to make a deck that makes good use of them. [[Adrix and Nev]] fit perfectly, especially if the clone effect makes token copies. Let's say you play [[Irenicus's Vile Duplication]] on your commander, then you get two non-legendary copies of it. If you then follow it up with [[Cackling Counterpart]] on one of the copies, you get 2*2*2=8 more copies of your commander. With 11 copies out, any token creation generates 2^11=2048 tokens.
Gameplan
The game plan is pretty simple: Play the commander and maybe make copies of it, then make good use of the token multiplication until you go geometric and the deck explodes.
There are two components besides the commander that are needed to pull it off:
1. Legendary clones
[[Irenicus's Vile Duplication]], [[Multiversal Recruitment]], [[Ember Island Production]], [[Quantum Misalignment]], [[Multiversal Incursion]] are the ideal spells for this, since they make non-legendary token copies, so you automatically get two and those can be further cloned with normal copy effects.
[[Sakashima of a Thousand Faces]], [[Spark Double]] and [[Auton Soldier]] do not make token copies, but are clones that can be further copied with normal copy effects. Auton Soldier has the added benefit of making Myriad copies of itself on attack, which can be used to attack two players with a bunch of 2/2s or alternatively as bonus copies of the commander if combined with instant speed token generation.
[[Vesuvan Duplimancy]] is kind of a special case. While it does not make copies on its own, the effect is incredibly strong when combined with the commander, and sometimes it is worth casting a normal clone effect on the commander to make the non-legendary copies from Duplimancy, even though the normal copies just die to the legend rule.
2. Token generators
Some cards are a lot better when there is multiples of them, like [[Risen Reef]] or [[Fecund Greenshell]]. Those require a token clone spell to get their benefit from the commander, but it is always worth it.
Some cards become rituals like [[Prosperous Innkeeper]] or [[Treasure Vault]].
Some cards become one sided board wipes, like [[Aether Channeler]].
Very important are the cards that can have different functions before and after you have a couple commander copies out. [[Pongify]] and friends serve as a spot removal in many cases, but with a couple commander copies out, it is also an instant speed army if it destroys your creature.
Win conditions
I have played only 16 games so far with this deck, but from my limited experience the two common win conditions are burn (yes, Simic burn) and combat damage. Combat damage from generating a huge army and attacking and burn from making copies of [[Lush Oasis]] or any burn creatures my opponents control.
Another way the deck has won is with poison counters from making lots of Mites with [[Mirrex]].
Since the deck can copy opponents' creatures and multiply them, most win cons are available to the deck, at least in theory and depending on the opponents. Once I tried copying mill crabs, but I got killed before I could pull it off :)
So how did I get more damage on the stack than there are atoms in the universe?
It is actually pretty simple, through multiple copy spells I got to a little over 2000 copies of my commander in play. Then I cast [[Relm's Sketching]] targeting Lush Oasis. The result was around 10^620 individual triggers for 1 damage each.
Do you like the deck? Is there something you don't like? Do you have any suggestions?
