Polaris on Mutate and Sporadic Creatures

3 days ago

@Rhadmanthus is right, but I just have to point out a small nitpick: if you have a merged permanent with a Vehicle (let's say Gemrazer mutated on top of Thundering Chariot ), activating the crew ability will still turn the merged Gemrazer from a creature into an artifact creature for the turn. This won't matter most of the time but you never know!

Mutate is an alternate casting method. You either pay that or the regular mana cost. Not both. Abilities that trigger off mutating either trigger off the card itself being cast via mutate cost, or, while already in the battlefield, being mutated by a different card that was cast for its mutate cost.

1B) Technically yes, the process to cast a spell is to first put it on the stack. The last step is paying the mana. If you do not have enough mana to pay the cost, the game reverses to just before you propose casting the spell. A spell is not considered cast until the cost has been paid. Though this has no relevance for your overall question.

2A) You are correct. It’s ability is triggered off of mutation. If it’s cast with its regular mana cost, it will not trigger the mutate ability.

2B) also yes. If it’s on the battlefield already, you can cast a second card for its mutate cost onto the Gemrazer , thus triggering its mutate ability.

2C) not sure what you’re asking. Refer to other answers.

epicPlain on Mutate and mana costs for …

Somehow I have difficulty to understand the mutate concept. Here are some questions:

1a) If I have Gemrazer in my hand during my turn, will I be able to put it on the stack without paying its casting cost and instead, pay for the mutate cost (e.g. )?

1b) Does 1a entail that any spell can be put onto the stack without paying mana (and if I can not pay for the cost it will not resolve)?

2a) If I pay the summoning cost , am I right in the assumption that it will not trigger its ability to destroy an artifact or enchantment?

2b) Instead, if I use a mutate spell on it, it will then destroy an artifact or enchantment.

2c) or else, I will have to pay his mutate cost (as in 1a) ) to trigger that effect mentioned in 2a) when the spell becomes a part of the mutated creature (after casting Gemrazer successfully for its mutate cost?

Sorin_Markov_1947 on Vorinclex the Finisher

You definitely want more Great Henge in this deck. It's card draw, counters, mana, life gain, and you'll get it out a good bit with strong creatures. Putting four in is not unreasonable for such a powerful card even if it is legendary, but at least put three.

Basri's Lieutenant is just incredible in a deck like this, as are Stonecoil Serpent (combine with Gemrazer ?) and Luminarch Aspirant . Consider The Ozolith as well, as it helps you recover if your countered-up creatures die, as they often will do.

If you need cards to take out, Iridescent Hornbeetle is probably one of the first to go. Return of the Wildspeaker is just okay, Kogla doesn't really fit the theme, and Cultivate doesn't either. You shouldn't focus so much on getting Vorinclex out as soon as possible. Focus on making your deck not reliant on him so that you can get wins when you never even draw him. A deck like this needs to be fast, so you can't really spend turns ramping.

Manabase. A little lazy here, just 26 basics and hit go. Put in some Castle Garenbrig as there's almost no downside to it, 4x Branchloft Pathway  Flip also no downside (except rare wildcards if you're not going to play Selesnya much) and gives some mana fixing, and that's really all you need. I can't think of other lands you benefit from.

There are some other Selesnya counters decks out there that are doing well even at higher ranks. I'd encourage you to look at them if you're struggling with your deck and see which cards are common and which aren't anywhere to be found.

You should add some Indatha Triome to your mana base to give you the option to cast Mythos of Nethroi to destroy any non-land permanent too.

You only have 2 creatures that trigger Garruk's Uprising so I'm not even sure why you run it, I would highly recommend you swap them for 3 Call of the Death-Dweller so you can bring back your very important Fynn, the Fangbearer along with a 1 drop death touch creature instead, with menace.

Running 4 Return to Nature main deck seems a bit much since it's still a situational card. You could swap 2 of them for 2 Gemrazer so you still have the ability to remove enchantments and artifacts, but also get to turn your small death touch dudes into big trampling death touch dudes with reach.

Hopefully these are useful, cheers!

Rhadamanthus on Lithoform engine copying mutating creatures

3 months ago

The copy will still be a mutating creature spell and will have the same target as the original. If a spell does something special when you pay an alternative cost, copies of the spell will also take that into account. Lithoform Engine's last ability doesn't allow you to choose a different target for the copy of the permanent spell, so it has the same target as the original spell.

The copied spell will resolve first, triggering any "whenever this creature mutates..." abilities that the targeted creature already has, and then the original Gemrazer spell will resolve, triggering those abilities plus the ability given by the copy.

To the bonus question: No, this won't trigger Season of Growth. It won't trigger the first ability because there isn't a creature entering the battlefield, and it won't trigger the second ability because the copied spell wasn't "cast".

If I have Lithoform Engine on the battlefield and cast Gemrazer for it's mutate cost targetting a creature, I then use the engine's third ability to copy that creature spell, will the new Gemrazer also mutate onto the creature I was trying to mutate or will it act like a new creature. If so can a "mutant token" activate new mutate triggers if I mutate it again.

Yes another mutate question

bonus question: If the new mutate token copied gemrazer does mutate, does it trigger Season of Growth
