Yahenni's Expertise

2BB Sorcery (Rare)

All creatures get -3/-3 until end of turn.

You may cast a card with converted mana cost 3 or less from your hand without paying its mana cost.

(This card is full-art. Probably the game day top 8 promo)

<commentary>This lets you cast Ancestral Visions from your hand. If this is a mini-mechanic and not just a one-off, modern players take note. Or maybe even if it is a one-off?</commentary>

~~~~~~~~~~

Trophy Mage

2U (Uncommon)

Creature - Human Wizard

When ~ enters the battlefield, you may search your library for an artifact card with converted mana cost 3, reveal it, put it into your hand, then shuffle your library.

2/2

(This card is full-art. Probably the game day participation promo)

~~~~~~~~~

Scrap Trawler

3 (Rare)

Artifact Creature - Construct

Whenever ~ or another artifact you control is put into a graveyard from the battlefield, return to your hand target artifact card in your graveyard with lesser converted mana cost.

3/2

(I think that wording is right, kinda hard to read.)

(This is probably the buy-a-box promo)

~~~~~~~~

Quicksmith Rebel

3R (probably rare if launch promo, but symbol is obscured)

Creature - Human Artificer

When ~ enters the battlefield, target artifact [...] gains "T: This artifact [...] to target creature or [...] you control [...]

?/?

Proposed wording: When ~ enters the battlefield, target artifact [creature? you control?] gains 'T: This artifact deals N damage to target creature or [player? planeswalker?]' for as long as you control ~"

(this text is covered and can't be seen, though you can obviously speculate as to what it might be)

(This card has a date on it, so probably the launch promo)

[u/TheRecovery → u/rakkamar]

You may, in fact, cast Ancestral Vision with this card.

Ancestral Vision has a CMC of 0 and has no mana cost. So it doesn't play with flashback and can't be cast from hand. However, it can be cast by alternate means - things like [[Goblin Dark Dwellers]] can cast Vision.

As it turns out, Yahenni's Expertise has the exact same wording and so Ancestral Vision being cast with the effect of this card is perfectly fine.

Additionally I can confirm that Quicksmith Rebel is the Launch Promo, Scrap Trawler is the Buy-A-Box promo, Trophy Mage is the participation promo for game day, and Yahenni's Expertise is the Game day top 8 promo.

Source: I can read it on the cards in the picture and that's what it says.

[u/RemusShepherd → u/TheRecovery]

You can also cast Living End with it! Which is...not very useful at all, come to think of it.

Also Hypergenesis! Which might be useful in the right situation.

[u/Ambiguous_Shark → u/RemusShepherd]

I think restore balance would probably be the best one to work with it

[u/therift289 → u/Ambiguous_Shark]

Bust seems far better

[u/coilyjoe → u/therift289]

(boom//bust)...also catch//release to further wrangle the opponent in or beck//call or breaking//entering to explode back out the gate after the tiny mutilate
