The MTG tap mechanic was patented, not copyrighted. https://patents.google.com/patent/US5662332A/en , claims 4, 5, and 6 - expired in 2014. The actual symbol is also a copyright and trademark, I believe, but right now other games can us the 90 degree rotation. (Disney's Lorcana, for example, uses 90 degree rotation and calls it 'exerting' a card.) |
