You’re right, I was focusing only on layer 6. Thanks!

I think in this scenario, on Layer 6 there's a dependency and so timestamp doesn't apply.

Appreciated Matt, thanks!

Thanks for your help!

Hello Matt! Quick question: Does rule 903.11 allow the use of Companions in Commander? If not, where in the Comprehensive Rules can I find the regulations for them? Thanks in advance!

No worries, Matt—thanks! \:D This creates a weird interaction, then. If I control a Doubling Season and play an Urza’s Saga, it should enter with only one lore counter, not two… I guess?

Thanks, Matt. However, I wonder what qualifies it as a replacement effect, since it doesn’t match any of the definitions in the CR (except for the “As this enters” template, which specifically belongs to some static abilities—and this is a rule, not an ability).

In any case, I’m afraid that players will find this interaction rather counterintuitive. In my opinion, making 714.3a an intrinsic ability might help the game work the way players expect without “breaking” anything (unless, of course, this design choice is intentional).

Because that “replacement” comes from a rule, and not from the card’s text. Nor is it an intrinsic ability of the Saga. So BM can’t remove it at all.

Thanks, Matt! Follow-up question: can what puts the first lore counter on a Saga be qualified as a replacement effect? It doesn't really match the definition of "effect" or "replacement effect", considering it comes from a rule and not from a resolving spell, ability, or static effect.

Thanks again Matt :)

So, the calculation to be performed is –3 – (–7), which simplifies to –3 + 7, yielding 4. Is that correct?

Thanks Matt!

Thanks Matt!

The "problem" is that, according to CR 508.1b/508.1c, affirmative sentences are presented as requirements, while negative sentences are presented as restrictions. This can be somewhat confusing when it comes to evaluating the two. "Can't attack except alone" could be an alternative option?

Great, thanks!

Thanks Matt! I was thinking about something weird also, like a lighting bolt put down as a 5/5 creature with Tezzeret, Cruel Machinist (it’s not manifested for the CR). Then I turn it face up with Ixidor and then I try to copy it with a Clever Impersonator.
Maybe that rule sets a default for this?

Thank you Matt! <3
