Gossamer Chains does say "target unblocked creature" so itcant handle the hexproof Commanders. The other recommendation I can make is to load up on the 2 cmc counterspells that target creatures- essence scatter, remove soul, preemptive strike, false summoning, psychic barrier, etc. Opposing Lawmages may have Hexproof but they can be countered.
The Bestow creatures cannot be tutored for by totem guide or heliod's pilgrim. The Bestow creatures only count as auras when they're attached to a creature.
In white/blue, dealing with opposing hexproof creatures is possible, such as:
Curfew
Any of the Circle of Protection spells (i like Rune of Protection because they cycle)
Moonlight geist- blocks their Commander
Exhume is a must in any type of Reanimator deck. Your opponents will never have the same level of fatty that you have in their graveyard. And when you cast it on turn 2 you're practically guaranteed being the only one to reanimate something.
Last night I got a game in. I didnt win because someone cast Austere Command leaving me with nothing but three lands, however having both Tangle Wire and Winter orb out on turn 2 felt satisfying enough. I think I drew my second land on turn 5, otherwise I would have gotten Kozilek out way sooner. The funniest part of the game was me allowing someone to attack me with a doublestrike Mindleech Mass so that he could cast both my Kozilek in hand and Blightsteel Colossus.
Composite Golem is better for 5 color combo; such a list actually exists in this forum.
I myself run Paragon of the Amesha to good effect. I like the lifelink more than being a 7/5. Late game i can pump Paragon numerous times to kill in two swings. Using 15 mana to make it an 11/11 late game happens often.
A friend of mine recently made Fleshformer, as a 5 color Allies deck with Changelings and Rebels to pull out more Changelings. As it turns out, recurring -2/-2 was very powerful, allowing him to essentially clear the board of utility threats, which PEDH has a lot of. He also printed out an altered art picture of Lord Vader using the chockhold, which was very flavorful and fitting for what the Fleshformer did turn after turn.
Im running Cockatrice as UG TurboFog, which has been fairly effective so far. It definitely fairs better once its down to me vs. one opponent. I exclude Viridian Longbow, Hermetic Study and Psionic Gift because I need to be attacking with my flying 6/6 in order to win the game; against numerous opponents I cant afford to ping only 1 creature per turn.
Wall of Hope seems a little unreliable for lifegain; Syndicate Enforcer is the least cost-effective Extort creature with zero defensive capabilities, and poor offensive capabilities (aka no flying). Soul's Attendant completes the cycle of the Soul Warden creatures, which in the course of a long multiplayer game can gain a lot of life, and Teroh's Faithful was added in as another defensive creature that gains 4 life without needing to extort, which should be more effective than the Syndicate Enforcer.
-Exploration
-Liliana of the Veil
-Sulfurous Springs
-Slice and Dice
-Dreadbore
+Courser of Kruphix
+Oracle of Mul Daya
+Tainted Wood
+Head Games
+Sarkhan Vol
Lands empty from my hand quickly anyways, and without a large number of hand refills Exploration loses its oomph. I decided to try the Courser and Oracle, as it helps smooth my topdecks and they're forms of ramp in the late game. Courser's lifegain is a plus.
Liliana of the Veil is powerful but is underperforming in my deck. +1 hurts me just as often as the opponent. Many times I'll take a turn and not activate either ability. Liliana also has no synergy when Prossh is on the battlefield. Im going to try Sarkhan Vol since I can always +1, the +1 pushes through 12 damage which is nice, the -2 synergizes very well with Prossh and acts as removal similar to Liliana's -2, and his ultimate is easier to achieve and more likely to end the game.
Trying out Tainted Wood to replace Sulfurous Springs.
I want to test out Head Games as Persecute #2.
Took out Slice and Dice as its the weakest sweeper.
I'm getting very close to being done. Here are the Celtic cards. Note: a few cards still need a card name, and I want to make some tweaks and changes with names and flavor text but the cart art and card design of all 251 is essentially done.
I'm excited for a lot of these new printings, and all the downgraded reprints with the exception of Dream Fracture. I simply do not see the benefit to playing an inferior Arcane Denial card at all.
Treasonous Ogre is interesting as a Commander but in Mono Red what do you do with 13 free mana? (Assuming you're at 40 life.) You could cast two 6 mana haste fatties, but then what?
Marchesa's Smuggler looks to easily be the most interesting Pauper Commander choice to come from the whole set; you look at that card and deck idea gears start turning. I'd try something out but I already have too many Izzet PEDH decks as it is.
The Looters are a good engine on their own. I have noticed in testing that since most of my shenanigans happen at Sorcery speed that I activate them on my turn anyways, so the Kor will likely come in as an addition rather than replacing another Looter.
Edit: Made some quick changes. Torrent of Fire is really bad. Mulldrifter only has synergy with Ghostly Flicker, as does Subterranean Shambler (which also kills my own utility creatures.) Encrust feels meh since it's not an instant or a sorcery. Mystic Remora is a great card, but I do not want it tying up my mana. Nullify has too few targets and loses it's surprise value, so there's much to gain by recurring it.
Looter il-Kor comes in as another looter. Vedalken Aethermage comes in as another way to tutor for Goblin Electromancer. Jilt provides just that bit of extra value that I would want in a bounce spell. Sift Through Sands is Catalog #2, and will probably just draw me more cards than Mystic Remora would. Withdraw is a great bounce spell that shouldn't have been omitted from the original decklist. Scouring Sands is a strange choice but I like that it kills all opposing utility creatures without killing my own (which was the biggest downside to Subterranean Shambler, has more synergy with my own Commander... with enough mana I might be able to cast it more than once in a turn and kill even bigger things, and the Scry 1 is helpful. Also if I have infinite mana/recasts it kills all opposing creatures while also scrying to a win spell.

Some other ideas:
Lotus Petal
Forbidden Orchard
Homeward Path
Bribery
Show and Tell
Traumatize
Forbid
Crystal Vein
Time of Need
Mesmeric Orb
