So I read about her and I read about prototype artifacts and new rulings about them. Yet not sure if this will work
You have Jhoira, Ageless Innovator on the battlefield, say with 4 counters on her. You tap to make her have 6.
Can you cast either one of these cards for free with Jhoira?
The reason I ask is that the Prototype value of both the cards are less then or equal to 6, and they are artifacts...
This is what I got from wizards
10/14/2022 - Regardless of how it was cast, a prototype card always has the same name, abilities, types, and so on. Only the mana cost, mana value, color, power, and toughness change depending on whether the card was cast as a prototyped spell.
10/14/2022 - The prototype ability functions in any zone that the spell could be cast from. For example, if an effect allows you to cast artifact spells from your graveyard, you could cast a prototyped from your graveyard.
10/14/2022 - Casting a prototyped spell isn’t the same as casting it for an alternative cost, and an alternative cost may be applied to a spell cast this way. For example, if an effect allows you to cast an artifact card without paying its mana cost, you could either cast the spell normally, or as a prototyped spell.
10/14/2022 - When casting a prototyped spell, use only its prototype characteristics to determine whether it’s legal to cast it.
With that said — MTGA - WON'T allow you to cast either cards in hand with Jhoira… and I believe you should be able to...
