Do not feel constrained by the order of the cards; mash together what you will. I chose 6 cards for each cog so that you may roll a six-sided die to determine which cogs get mashed together, if you so wish.

Cog A:

Cog B:

Cog C:

And, yes, this is a difficult challenge. I suggest avoiding looking at the cards literally, and to only take one or two elements from each card to make your final card. Super bonus points are rewarded if you can somehow mash all three cards onto one card, then find space for a triple mash of flavor text--but that's certainly not expected.

­Demon of Might tried again, and got Overwhelming Knowledge. Which, uh, mashes an additional card or two, because, um.

­Mirari's Embrace from Gaea's Embrace, Mirari, Nullmage Advocate.

Added Entrancing Gibbersong.

I made Seething Mirari and forgot to mention that here.

Created Spirit of Circling Life from Spearbreaker Behemoth, Gibbering Kami, Sylvan Echoes.
Created Soul Tether from Biting Tether, Demonic Consultation and Talas Researcher.
Created Abolisher Guildmage from Biting Tether, Azorius Guildmage and Razorfin Abolisher.

­Sylvan Magetether

­Regenerating Card Bears

This challenge is insanely hard because many of the cards are already about many things at once (so, for example, neither a mere life gain nor a draw spell really evoke Kiss of the Amesha).

Made Zhur-Taa Guildmage.

Created (((Tethermage Researcher))) from Binding Tether, Azorius Guildmage & Talas Researcher. ­
Used the Guildmage as the body & Binding Tether & the researcher as the two abilities (balanced for modern card design). ­
I set the cc at as that would mean you could use the steal ability on turn 5 (around when you could cast a steal creature enchantment/sorcery etc). I used Divination as a guide for the draw ability cost, its for 2 cards but as the ability is repeatable you only get 1 card.

­Dwarven Seethbolishing

I created Fan Collector from Kiss of the Amesha, Mirari and Soul Collector.
Then I created Seethmage Catapultist from Seething Song, Dwarven Catapult and Nullmage Advocate.

Finally, I created Ruthless Alpha from Gaea's Embrace, Hooded Kavu and Outbreak.

Created the card Souls Devastation from Combining Devastation,Gibbering Kami and Outbreak
