Unstable Glyphbridge // Sandswirl Wanderglyph

If Sandswirl Wanderglyph leaves the battlefield on a turn in which an opponent attacked you or a planeswalker you control (perhaps because it died in combat or another player cast a spell that destroyed it), that opponent can cast spells.

The back faces of some cards with craft refer to cards "used to craft" it. This refers to the cards exiled as part of the cost of the craft ability of the front face. Those cards are considered to be "used to craft" that permanent as long as they remain exiled and the permanent remains on the battlefield, even if the permanent's controller changes or some of its characteristics change (because of a copy effect, for example.)

In Two-Headed Giant, for each attacking creature, the attacking team announces which defending player, planeswalker, or battle that creature is attacking when it's declared as an attacker. Sandswirl Wanderglyph's abilities care only about creatures that attack you or planeswalkers you control, not creatures that attack your teammate or planeswalkers they control.

Unstable Glyphbridge's first ability triggers if you cast it from any zone. It doesn't trigger if you put Unstable Glyphbridge onto the battlefield without casting it.

Sandswirl Wanderglyph's abilities won't stop opponents from attacking battles you protect or casting spells after attacking battles you protect.

If the materials required include multiple objects, you may exile some of them from among permanents you control and the rest from among cards in your graveyard. You don't have to choose all permanents or all cards from your graveyard.

If a card that isn't a transforming double-faced card becomes a copy of a card with craft, it'll stay in exile if you activate the craft ability. It won't return to the battlefield.

For each player, including yourself, you must choose a creature with power 2 or less to save if you can.

Once Sandswirl Wanderglyph's middle ability resolves, that opponent won't be able to attack you or planeswalkers you control that turn, even if Sandswirl Wanderglyph is no longer on the battlefield.

You may exile tokens you control as part of the materials required. However, because they aren't cards and won't stay in exile, any abilities that refer to what you "used to craft" the back faces won't refer to anything.
