Big Bang - 5RRR
Sorcery (M)
Exile all permanents you control. Put all permanent cards in your hand onto the battlefield, then cast all non-permanent cards in your hand without paying their mana cost. Afterwards, put all the cards you exiled from Big Bang into your hand.
Kavu Instigator - 2RG
Creature -- Kavu (U)
When Kavu Instigator enters the battlefield, it fights target creature an opponent controls.
4/2
Conservation Orb - 2
Artifact (R)
When Conservation Orb enters the battlefield, draw a card.
Players can't sacrifice lands.
Lands without a mana ability gain "T: Add 1 to your mana pool."
Banecircle - 1W
Enchantment (R)
As Banecircle enters the battlefield, name a card. 2: The next time a source of your choice with the same name as the named card would deal damage to you, prevent that damage.
Big Bang - Oh my. What an excellent red "chaos" card. I like this a lot, and I can see it occupying a place in ramp-related decks just like Omniscience or Dragonstorm.
Kavu Instigator - This is way fairer than Flametongue Kavu, of course, but still strong. An interesting riff.
Conservation Orb - Tbqh, there are already fringe hosers for fetchlands, like Mindlock Orb and similar. That last ability makes it sort of wacky-interesting though.
Banecircle - I'd always, always play Runed Halo over this. An interesting concept, but one that you were beaten to; not your best effort.
Conservation Orb is a card I like a lot. I feel like the draw a card is a little forced. Maybe this could be a red or green hatebear or maybe it could be an artifact with the draw for CMC 1.
