CURATOR COMMENT-You forgot the '
' icon for the upgraded card's Cost section in the table (add it in)
-Leave the ATK|HP section of the table blank if the card is not a creature
-Your art is 'questionable', but perhaps acceptable...
Compared to other 'environmental' effects, Desert doesn't seem to provide any logic in terms of its mechanic. Suppose you were to play an Arctic Squid in a water-time duo - how would playing Desert (a Time card) actually improve an Arctic Squid's health pool (a Water card)? It makes sense for Time creatures, but for anything else, it might not (especially creatures that wouldn't want to live in a desert per se...).
Would this affect burrowed creatures? Immortalized ones?
