Where to go from here?

[Colossus]

I started with the PhoeniXplosion deck unupped and grinded through Ai3 till I had 10 cards upped now.

I have:

6 Creamtions
2 Burning Towers
2 Minor Phoenix

All upgraded and the other 20 not.

I'm wondering where to go now though? I'm looking for a great t50 and maybe Half Blood grinding deck. Then eventually to a FG deck, probably a rainbow like CCYB or something like that.

I don't mind grinding now to earn the electrum to fund that deck, just not sure which deck would be the best to aim for?

Hope that blabbering makes sense.

Thanks for any and all help.

Honestly, upgrade 4-5 more Burning Towers and build a Cremation/Photon/Burning Tower (6 of each) engine that can consistently get a Crimson Dragon down on the 1st-3rd turns, and grind t50 for 2 green Shards and 3 Lobos, then grind AI3 for enough cash to upgrade the Shards, then enough cash to upgrade 6 Photons to Rays of Light.

Then, start playing RoL/Hope vs. FGs.  That's the quickest way you'll get cash for more upgrades starting from where you're from.

Thanks Essence.

I have 6 unupped shards and the Lobotomizers too.

I guess it's back to grinding the crap out of Ai3 for me then.
