False God-W/L/(EM)-Short note
Akebono-6/4/(6)-SoFo is annoying.
Chaos Lord-6/4/(3)-Mostly fine unless he gets a mutant with steal or destroy.
Dark Matter-3/7/(2)-Depends on drawing enough bone towers.
Decay-1/9/(0)-Decay counters SoX perfectly and stolen SoPs are bad.
Destiny-10/0/(10)-Yes, that's 10 EMs out of 10 games. No PC, no QC, and she won't touch the cells.
Divine Glory-4/6/(0)-Too many explosions.
Dream Catcher-5/5/(0)-Strangely enough, it's possible despite all the PC and QC.
Elidnis-10/0/(9)-AI doesn't even bother to lobotomize the first cell.
Eternal Phoenix-1/9/(1)-Copious explosions, heavy burst damage, and firestorms (which he will, in fact, use) make this near impossible.
Ferox-8/2/(8)-No control, but the fast damage means bad draws can be lethal.
Fire Queen-8/2/(8)-No control, but running out of SoX late is easily instant death, even with dials, because of lances.
Gemini-8/2/(7)-Again, no control, but his hand tends to clog with TUs and the drawpower is necessary to get the explosion against a shield chain.
Graviton-5/5/(4)-Like Eternal Phoenix, but easier. Gravity Shield is annoying.
Hecate-6/4/(3)-Tricky with steals and damage around dials.
Hermes-0/10/(0)-It's impossible.
Incarnate-8/2/(7)-Bonewall and late SoPs are scary.
Jezebel-2/8/(0)-Everything gets stolen.
Lionheart-10/0/(9)-Has yet to learn about the nutritional benefits of cells.
Miracle-10/0/(10)-No comment.
Morte-7/3/(5)-Very tricky because bonewall rules out OTK. Offensive afla does wonders to prevent viruses and light quanta for Miracle.
Neptune-8/2/(5)-Neptune is not a formidable opponent. The RNG is.
Obliterator-5/5/(1)-Diamond+pulvy blocks all damage.
Octane-0/10/(0)-Octane sucks.
Osiris-9/1/(8)-See Akebono and Lionheart.
Paradox-10/0/(10)-No dangers except a TU blitz.
Rainbow-5/5/(1)-Too much PC. [Trainer can't handle 60 card decks so I dropped one Congeal from Rainbow's deck.]
Scorpio-6/4/(2)-Scorpio has poison to nullify dials and Purify to erase SoX.
Seism-10/0/(9)-Earthquakes are not much of an issue, since only one afla must be played.
Serket-10/0/(10)-Drawpower is very easy to get and the poison won't stack up during a dial chain.
