More spoilers guys. You've been patient, now it's time for you to be rewarded!
I haven't put the commons/uncommons up, only the rares I think could be of interest to you.
Artefacts I'm not sure if these artefacts,
Crucible of Worlds notwithstanding, will have an impact on Standard/Limited or Modern -
Amulet of Safekeeping is low enough on the curve that it could be annoying to control/ramp decks. Which is especially good for mono red/white decks. The tokens effect is a little punishing - that said, there are not many in standard, currently.
The
Magistrate's Scepter looks fun, especially when you can use cards to circumvent its 4 mana ability -
Energy ChamberMulticoloured Welcome Elder Dragons - Wait... Aren't they 'mostly' all
dead? Who cares! I like Arcades and Palladia the most!
Assault Formation on a Dragon! Not to mention the
Dragonlord Atarka reminiscent Palladia.
Oh, yeah
Nicol Bolas, the Ravager - He is disgusting, as HowlingLotus has said, but in the best way. Even if he dies you can flip him by exiling from your graveyard!
Green Elves tribal is looking strong going into M19. With
Steel Leaf Champion and
Marwyn, the Nurturer supporting the theme from Dominaria it looks viable.
Red Goblin tribal could actually be a thing, especially after rotation puts out Kaladesh and Amonkhet - assuming
Goblin Chainwhirler isn't banned in the upcoming announcement (July 2nd)
The Dragon theme looks pretty viable, especially when you can ramp into them using the new
Sarkhan, Fireblood. Whilst he doesn't protect himself, the mana cost is low enough, for him to be an early threat with the loot ability or ramp function. - Turn 4
Glorybringer?
Black It looks like Wizards are trying to push as many tribal themes as they can, before rotation. Zombies, an example, which was dominant before Shadows over Innistrad rotated looks poised to repeat its dominance. Maybe? With
Death Baron reprinted, and currently at 90% its original cost, it could be a nice budget brew.
Phylactery Lich is a powerhouse! Combine it with something like
Darksteel Myr, or
Amaranthine Wall?
I have to say,
Liliana, Untouched by Death, is one of the weakest reiterations of her to date. Self-mill without the payback of
Liliana, Death's Majesty makes it vastly unplayable- Unless you are willing to -3 her and cast a zombie from your graveyard (you still have to pay its mana cost), which isn't much of an advantage unless you are in a
bind. Then again, why pay 4 to cast a spell that lets you recast a zombie from your graveyard when you can play something better?
Blue Blue is doing what it does best, enchanting and spell slinging. The
Supreme Phantom is a nice card. However, it lacks spirit support in a limited format, especially standard, currently.
One with the Machine is a crazy sorcery in conjunction with Requilary Tower and
Metalwork Colossus. (Just an idea) Finally
Sai, Master Thopterist is one of those cards that make you hate people that play cheesy combo decks like
Paradoxical Outcome and
Aetherflux Reservoir...
White These are by far my favourite, of the spoilers.
Resplendent Angel is a card I know will be played. It is just such a threat, and whilst it is difficult to gain 5 life in a turn, who would want its ability to trigger? Isolate is a nice little niche card, something that would fit into your sideboard in Modern against something like
Zurgo Bellstriker or
Goblin Guide.
Cleansing Nova is obviously for those
Karn, Scion of Urza decks which could potentially make artefacts dominant after rotation in Standard? Finally
Ajani, Adversary of Tyrants. This is the card white needed after
Gideon Ally of Zendikar rotated out of standard. They have been missing a good mono coloured planeswalker.
Gideon of the Trials is not that great... Let's be honest. The -2 ability is incredibly useful, especially with
shock still in the format after rotation. We just need some good 1-2 drops to utilise this ability. Even so, the +1 is useful in conjunction with
Legion's Landing, and other token generators.
Anyway, I've rushed through this, but I hope you've liked the commentary/ spoilers!
