Whether you're brewing a new Commander deck or trying to remember the name of that one card that draws when a creature dies, you need a good card database
But these things are also beautiful, if you just stop and look at them, and TCG Pocket carries that beauty over surprisingly well, most obviously with the handful of snazzy "immersive artwork" ones that take you on a guided, 2.5D tour of their own little goldfish bowl worlds
Rules [edit] A new card game starts in a small way, either as someone's invention, or as a modification of an existing game
On a 1, remove all +1/+1 counters from this creature
While this is another topic I could again delve deeper on, Ill leave it at this: as games move toward ending in 6-8 turns (versus 8-10), cheap blowout interaction is the fastest way to gain tempo while protecting your board
