Rhadamanthus on Lier and Adventure Spells

Things that happen "as" you're taking an action happen as part of the action and before it completes. The choice to cast the adventure part of an adventurer card happens "as a player plays" it, meaning it's a decision you make before the card actually moves to the stack in the first part of the casting process. 601.3e makes a specific exception for mechanics that tell you to use an alternative set of characteristics to determine casting legality. The card gains flashback as it moves to the stack from the last sentence of 601.3e: "Continuous effects that would apply to that object once it has those characteristics are also considered". There's no "in-between zone" that the card is in while it's moving from the graveyard to the stack, so if it's not on the stack yet that means it's still in the graveyard and gets flashback. I don't like it either, but this is how the rules cause these weird effects to interact.

Note that several adventurer cards wouldn't be able to function properly without the exception granted by 601.3e. Consider something else about Giant Killer mentioned in the CR's example: Chop Down is an instant but Giant Killer itself doesn't have flash. The card in your hand only has Giant Killer's characteristics, so if the rules required evaluating the legality of casting from your hand before considering Chop Down's characteristics, you would only be able to cast Chop Down at sorcery speed, since there would otherwise be no rule or effect allowing you to cast Giant Killer at instant speed. Also consider a card like Midgar, City of Mako. If you had to make the legality determination for casting Reactor Raid based on Midgar's characteristics, you wouldn't be able to start casting Reactor Raid if you'd already played a land this turn.

If I remember correctly, earlier versions of the rules that might not have worked this way had to be changed to solve some issues with modal double-faced cards, most notably an unintended interaction that caused a problem in Modern where people would cascade into Valki, God of Lies and then get to cast the Tibalt, Cosmic Impostor side for free.

It is, but if they didn't do it that way there would be a ton of game-breaking weirdness that could ensue. They actually had to change how cascade worked recently (like on Violent Outburst) because it was letting you cascade into Valki, God of Lies  ^Flip and cast it as Tibalt, Cosmic Impostor for free on turn 2 or 3.

sergiodelrio SSG was banned super-recently, so there’s zero chance they’re unbanning its twin. Wotcs official statement on the SSG ban was

“ Simian Spirit Guide is a card we’ve had our eye on for some time as an enabler that speeds up fast combo decks.

To slow down that category of combo decks as a whole and give opponents more time to set up interactive plays in the early game, Simian Spirit Guide is banned.”

In general fast mana is an issue prior to turn 2. The big reason the card got banned to begin with was at a time when people could abuse it with Cascade to get out a turn 1-or-2 Tibalt, Cosmic Impostor. The rules for Cascade have since changed, but the risk fast mana in general poses remains, although admittedly Rite of Flame having a cmc of 1 makes it harder to abuse in some of the shells SSG thrived in.

Storm does still exist, but admittedly not with any meaningful percentage. I’m probably channelling my local meta a bit too much there - which has a few storm decks.

Ugh sorry, but finally: I think Tibalt, Cosmic Impostor can be cut for similar reasons as Gonti; at MV 7 I think a card should give you a great advantage within a turn at least, but Tibby is a typically gradual value 'Walker.

THAT'S IT, NO MORE NITPICKING FROM ME

(...I hope...)

aszubat on Modifying a Rogue Mill Deck …

Mtg_Mega_Nerds your idea helps me create a rogue deck. But it doesn't really solve my problem. The deck I found is a blue and black deck. Because of that I don't have the red mana to play Tibalt, Cosmic Impostor . I'm searching for a way to eddit the deck I found (because I would like to keep the mill properties) that allows me to play Tibalt, Cosmic Impostor and deffend him so that he's acutally useful. I don't want to simply add red mana, because I think that could destroy some of the synergie with other cards (after all cards like Soaring Thought-Thief and Thieves' Guild Enforcer can do nothing with red mana). That's why I asked if Replicating Ring could do the trick or if there are better options to solve my problem.

If I have a Thassa, Deep-Dwelling and bounce Valki, God of Lies  ^Flip can I have it come back as Tibalt, Cosmic Impostor

Yes, simply just put the back side within double brackets like: Tibalt, Cosmic Impostor

Neotrup on How does Narset, Enlightened Master …

Narset, Enlightened Master lets you cast noncreature spells from among the exiled cards. As long as the spell your casting is a noncreature spell, such as Tibalt, Cosmic Impostor  ^Flip, you are aloud to cast it, even it it's a creature card like Valki, God of Lies  ^Flip. Similarly, if Bonecrusher Giant is exiled you can cast Bonecrusher Giant. This does require the noncreature spell to be cast normally, not with an alternate cost, so you can't cast Hypnotic Siren using bestow.
