For instance, if Brenard, Ginger Sculptor creates a copy of Awakened Amalgam, is the token a 1/1 (3/3 because of Brenard's first ability) or does awakened amalgam's ability override its base 1/1 power and toughness?

Similarly, what happens if you play Biomass Mutation while you have an Awakened Amalgam on the battlefield? Does Awakened Amalgam's power and toughness change to X/X until end of turn?

Consider replacing Saprazzan Heir, Slippery Bogle, Avacyn's Pilgrim, and maybe maybe Boomerang.

Consider adding Plague Myr, Quirion Elves, Viridian Corrupter, or Biomass Mutation.

• Looking to increase the presence of 1. Infect, 2. Elves, 3. Multi-Color Flexibility, 4. Legendary Creatures, and 5. 1/1 Creatures that are worth it.

Infect needs to have presence to be worth it and to combo with Exalted.

Elf presence makes tribal perks from Allosaurus Shepherd worth it.

Good 1/1 Creatures allow both legendary lands to give value when board is brought down to base power 1/1 through Humility or Godhead of Awe.

It is also helpful to bring most creatures CMC to 2, so that Uncage the Menagerie is more flexible in that range and has better ROI for mana spent.

Max_Hammer on Kadena "Surprise tool for later" …

1 year ago

I'm upgrading a Kadena, Slinking Sorcerer precon all about that one Micky Mouse gif where he goes, "And this is a surprise tool for later!" I want to know all of the fun mechanics where I can hide away (Hey... Wait a minute) a card and use it as a tool for later.

I've also chosen to lean a bit more into saccing creatures for draw or chump blocking them and putting them back into my hand, for a second use of their morph if need be.

I'd also like to note that my wincon is playing control (with hidden cards basically acting as loaded guns under the table), until I get one of my wincons out to storm the table. I have Vraska, Golgari Queen, Vraska the Unseen, Biomass Mutation, and Overwhelming Stampede in here alreay. I simply adore all Vraskas and Stampede/Mutation can usually turn my army of 2/2s into something lethal. And I know these aren't super optimal but again it's a precon upgrade, so do keep that in mind.

Of course we have morph and manifest, as well as foretell and hideaway (but only in the form of Watcher for Tomorrow (which I thought of whilst writing this), but are there any others?

Any suggestions for spicy stealthy mechanics, stronger/more consistent wincons (that aren't infinite combos, since this is casual), or improvements to the deck in general would be greatly appreciated as well. I've made some edits already but don't worry about suggesting something I've already seen.

Link to the precon decklist.

You can put Anthems in your deck if you want!

From the Official Gatherer website: https://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=562478

"A creature's base power and toughness are the power and toughness printed on the card"

"If another effect sets a creature's power and toughness to specific numbers or values, those become its base power and toughness" (That means cards like Biomass Mutation)

"If an effect modifies a creature's power and/or toughness without setting them (e.g.: Glorious Anthem), that is not included when determining its base power and toughness."

But your card choices are already great, so not a major loss :-)

One other planeswalker I would maybe suggest for you, is Ajani, Adversary of Tyrants!

Misconception on Zaxara, the Exemplary | X Gon' Give It to Ya

Once again thank you so much KongMing ^-^/

I have added Biomass Mutation right away since I really love the card! Especially since it's an Instant, I'm sure it can become a suprise kill.

I have thought about Iridescent Hornbeetle since I do have one in my collection, but I'm not sure if it will stick well enough to the table in my Pod to be worth the 5 mana... Probably gonna playtest it anyways tho!

Idk why but Plaxcaster Frogling is hilarious to me xD Love the lil' Dude! I'll have to see how the deck does with the protection I currently have but I'm happy to have some backup options for sure!

Walking Ballista used to be in the list but ultimately ended up simply being a flavour cut.

Spent some time thinking about some more adds.

Biomass Mutation could be a great way to give a big buff across your board, since so many of your hydras (including your tokens) are base 0/0. Instant-speed on it make it a great way to take someone down by surprise. (Just realized you already have this one! xP)

Iridescent Hornbeetle only activates on your end step, but you have a lot of sorcery-speed and creature X spells that would still activate it when Zaxara is out. Basically is just adds more efficiency - now in addition to getting an X/X hydra, you also get X 1/1 insects on end step.

Plaxcaster Frogling might help to give you some more evasion.

Since you're going infinite with mana anyways, how about Walking Ballista as a mana sink to finish the game?
