Just had a beautiful idea. One side has Kelaino and a sunriser, the other has any unit+gargantuin grow next to the sinriser and an oropsisaur.
If factions could use the cards of other factions
I would take Assassin Protocol to give my Swarmking Scarab Rush.
Or you know, give Aymara to Abyssian.
I would not be able to handle consuming rebirth or blood echoes…
Don,t forget the worst of all duzt already mentioned
Lyonar with flash
We could make a Golem Ebon Ox deck. Dreamshaper for hand refill, and a disgusting Sirocco finisher. 
Hmm…Ice Age with Ox though… 
discoverable
15chars
cadence on magmar
no words needed
lionize revenant with cycle abjudicator + darkfire
potential out-of-hand win
mnemovore abyssian but beside darksac you have flashjata too
visionar in songhai
surgeforger + mirkblood + abyssian swarm
gate + gigaloth in the same builder deck
godhammer swarmbyssian
obelysk + deathwatch
auroara + all faction swarms
faie, both wisps, manakite
doom in vanar. just think of how consistently they ramp up to 9 mana so early. imagine playing DOOM on turn 3
Bangle + Grimwar/Twin Fang
Tectonic Spikes in Songhai
Carrion Collector/Lurking Fear + Malicious Wisp
Mist Dragon Seal/Juxta/Heart Sister + any Magmar deck
Sandswirl/Hailstone in Starhorn
Why not mana vortex aswell?
I heard that infinite combos that interact in that way stopped after a while.
Yeah the only infinite combo which works is Shadowdancer + Kujata + Snowchaser but only because Snowchaser needs to be played again 
You know, guys. Crescent Spear/Alkyone + Deep Impact.
Target’s Health -1 +1.
I believe deep impact doesn’t deal damage
Effect:
Deal damage to a minion to reduce its Health to 1.
It pops forcefields and all, it even lets the health counter red.
Hmn… what about Ripper into Greater Fortitude into Abhorrent Unbirth? Could give more burst to that combo with attacking with Ripper once and then playing Unbirth.
seismoid + double kujata + nightmare operant +mirrorim + twin fang + plus more 1 health bullshit = infinite twin fang otk
Unbirth with any keyword-wise strong faction is just OP anyways, seeing as Shadow Reflection exists too
In a less OP context, Shroud Fugitive on
