CURATOR COMMENT
-Capitalize the word 'Spell' in the TYPE section of the non-upgraded table
-*Try to make the grammar a little more fluid - add the highlighted changes like so: "Poisons both players for 5 and causes 1 creature to be diseased."
* = suggestion
Other than that, simple changes - it's much more sensible to include a specific number with the revised card concept, since the 'X' on the other card may not have been so clear, even though people would also have to look at your Infectious Mass card as well...
