It would be easy to make an adventure-focused game similar to the Game Boy version, but add in features of the current online TCG experience
Notable Cards: Koby (OP11-001): Leader card that offers flexibility in gameplay
Recommended For: Orzhov Lifegain (Ayli, Eternal Pilgrim) RED Immolating Gyre Immolating Gyre reminds me of a less flexible/reliable Mizzium Mortars: you don't have the cheap targeted mode and you're not guaranteed 4 damage like Mortars, but in a Spellslinger deck that can quickly and consistently fill the graveyard with instants/sorceries, Gyre can start taking out even the biggest opposing creatures / walkers
Now if this could damage any target's it'd be on my top ten for sure
Creature - Elemental Color tag templates(None) Burn (CTRL to add secondary) Counters Qty: 2 Price: $99.98 Bristly Bill, Spine Sower Landfall Whenever a land you control enters, put a +1/+1 counter on target creature
Remember, cheap instant and sorceries, especially removal, can often beat powerful cards even late in the game
