Hi mark thanks so much for your blog.It must happen sometimes you work on a mechanic or card that everyone understands how its supposed to work and its clear what that card wants to do but the rules of the game cant technically allow for it to work. Can you share an example of something that seems simple but has never been done because of a rules issue?

The best example would be to look at the acorn cards of Unfinity. While a few we’re kept acorn for Legacy concerns, the vast majority of acorn cards simple don’t work in the rules. Here are some I get asked about all the time: Claire D'Loon, Joy SculptorFar OutGoblin BlastronautsGrand Marshall MacieHow Is This a Par Three?It Came from Planet GlurgLila, Hospitality HostessSolaflora, Intergalactic IconSole PerformerTrigger HappyTruss, Chief Engineer

Hi Maro! Need un-judge-help! Can Truss, Chief Engineer turn a -N effect into a +N effect, or is the number itself being modified, not the value+number? Examples:Can Truss change a Planeswalker's -1 into a +2?Can Truss change a -1/-1 effect into +2/-1?

The number is being changed.

What happens when you use Truss, Chief Engineer's ability to change the ranges on a card like Contact Other Plane so that the die roll values overlap, and you roll one of those overlapping values? Do you get both effects?

Yes.

I have some Un-Rules questions for Truss, Chief Engineer. First: Are First/Second & Once/Twice number words? Second: Can Truss change the Visit requirement for Attractions after you've rolled the Dice? Third: If someone casts Last Chance, and change it to "Take an extra turn after this two", does it counter the spell since it no longer makes sense or does nothing happen? Same question for any card that says "Up to one target card", does Truss stop the card from working by making it say Two?

First: No.Second: No.Third: If the new wording doesn’t make sense, it reverts to the old wording.

You said a card that grants convoke was an if, but it already exists: Chief Engineer.

I think they were asking for a card that gave all spells convoke.

I liked todays article, will you be talking about Chief Engineer?

Not in this series. I only had two columns worth so I had to limit how many cards I talked about. I do like the card a lot.
