This is not new. Every 'normal' Werewolf from Innistrad (excluding Emrakul's corruptions from Eldritch Moon) is a Human Werewolf on front face (sometimes with a third type too) and just Werewolf on back face. However, "Soldier" would make me think that perhaps it's a white Werewolf. Most Soldiers are white.
Tarmogoyf and most Lhurgoyfs (except the ones from Odyssey block) are */*+1 and thus would survive without abilities as a 0/1. But any creature that uses */* (whose P/T is defined solely by their textbox) dies on the spot.
They are still mana abilties. Nothing has changed about it. The new wording doesn't change any rules or interactions - just a shorter phrasing for the same timing restriction. A mana ability is an activated ability that doesn't target and isn't a walker loyalty ability. That's simply a timing restriction that says you can only activate it when you can cast an instant - thus you can't pop them while you're in the middle of casting a spell.
I just answered about the Lion in my prior post. Because the Lion is a homage to LED, which has that restriction for when it was made, you couldn't use LED to cast a card from hand.
As for Urza's Saga - it's literally looking for an artifact that has a mana cost of 0 or 1 - nothing else. It has to have a zero symbol or a 1 symbol.
Diamond Lion says 'Activate as an instant' as a timing restriction, nothing more. It's still an activated mana ability and resolves immediately.... but you can only do it when you have priority, so you can't pop the Lion while you're in the middle of casting a spell like you can with almost every other mana ability.
When the original Lion's Eye Diamond was made way back in 1996, the rules were much murkier and indistinct - it was a time when you had to activate your mana up front and it was impossible to use LED to cast a spell from your hand. When the 6th Edition overhaul happened in 1999, a 'you can only activate this as an instant' line was added. It used to say 'Activate this only when you could cast an instant' until recently.
This Lion is obviously a homage to LED.
And no, you can't use Voidslime on any activated mana ability for they don't use the stack.
Magecraft is in italics - meaning it's an ability word with no rules meaning.
So it seems to be a collection of abilities that trigger when you cast or copy an instant/sorcery. It would have no other requirements for it's not stated on the card.
Well, not strictly better for you can technically use Act of Treason to simply untap your creature and/or give it haste - you don't want to do that with this one for the destroy Equipment clause is not optional. But even so, this is a great card.
If Sakashima copied Akroma himself, and then you used Will on the Sakashima, then all the creatures will be Akroma with Sakashima's 'ignore the legend rule' text for copy effects can copy other copy effects.

AFR is an exception because, though it's not a Magic property, it IS a Wizards of the Coast property so it got to be Standard-legal.

Post blink he is a new object and refreshes his "hand" of spells.
Nope... 3 spots after this Sword are open.

Nope - Asceticism grants hexproof which makes Ruxa unhappy.

Faker, faker, cheddar baker.

The only snowflakes I care about are those in mana symbols. This could be confirmation that Kaldheim is a snow-related set.
