Expansion / Explosion Discussion

As much as it pains me, I might have to go with Armageddon. Sucks, especially since I wanted MLD to be a sub theme in the deck. But, I just can’t really afford to cut another draw card and fall into the “lack of” problem again. Plus, Expansion / Explosion at least can serve as a copy counter card if need be.

Expansion / Explosion or Armageddon are cards I would consider optional enough to cut!

Hey, on a budget well done upgrading the precon. Nice upgrades of Ral with Reverberate/Vengeance for the combo, Settlement/Encampment/Drum, Hippocamp, Brainstorm, Dig, Within, Shift, Passage.

Some budget cards to consider adding:

  • Narset's Reversal: can be repeatable for two mana to copy any instant/sorcery that's cast. The copy that Kalamax makes can target and bounce the original Reversal back to your hand to cast again on the next turn and Kalamax can make a copy of one instant on each player's turn.
  • Expansion / Explosion: another Fork to combo with Ral or a mass draw/damage spell with lots of mana.
  • Gravitic Punch: with Kalamax and a Fork this can kill three opponents and cast it again from your graveyard.
  • Cultivator's Caravan: three drop rainbow mana rock that can also be a repeatable source of tap for Kalamax (crew 3 is another instant way to tap Kalamax).
  • Return of the Wildspeaker: it can draw a lot of cards with high power Kalamax and/or give Kalamax/Drakes/Birds/Elementals +3/+3 or even +6/+6 to potentially kill one/more opponents.
  • Roiling Regrowth: like Harrow, but the lands ETB tapped.
  • Cascade Bluffs: Double Masters version is less than $4.
  • Shivan Reef: Commander 2020 version is $1.
  • Rootbound Crag
  • Sulfur Falls

If you like any of these suggestions I offer more advice about what cards to cut. Good luck with deck.

Gidgetimer on Can Expansion Copy Replicate?

3 weeks ago

You answered your own question in the question. Split cards only have the characteristics of the half being cast while on the stack. Therefore; Replicate of Repudiate / Replicate is a 3 mana sorcery and is a valid target for Expansion of Expansion / Explosion.

708.3b While on the stack, only the characteristics of the half being cast exist. The other half’s characteristics are treated as though they didn’t exist.

DemonDragonJ on Can Expansion Copy Replicate?

If a player casts the replicate half of Repudiate / Replicate, can they copy that spell with the expansion half of Expansion / Explosion? I would like to imagine so, since a split card has only the characteristics of the chosen half when it is cast.

DemonDragonJ on Charms or Split Cards?

3 weeks ago

I currently have in my red/blue/green deck a copy of both Izzet Charm and Simic Charm, which I put in that deck because of their versatility, but I find that they are useful only on occasion.

I am contemplating replacing those cards with Expansion / Explosion and Repudiate / Replicate, because those cards will be far more useful in that deck (specifically, for the first mode of the first card and the second mode of the second card), but I wish to seek the advice of the other members of this forum before I make such a change. What does everyone else think about this? Should I replace those two cards?

DemonDragonJ on Elemental Storm

I am contemplating replacing Izzet Charm with Expansion / Explosion and Simic Charm with Repudiate / Replicate, because the split cards would work far better in this deck than would the charms; what does everyone else think about that?
