Hmm... Tick could be a life card. The text could be: Automatically played when drawn. It can be qunta denial, a leech, and space denial all rolled up together. While I'm not fond of the whole "give a opponent a creature" mechanic people keep using, this is the best take I've seen so far.
And then you just make it the same thing as a antimattered vampire, although you could call it something else. Then it can just have the stats -1|1 and maybe the vampire status.
Off-Topic: Maybe the Vampire status should be changed to the the Leech status when antimattered. This whole business with the reverse vampires could use a new name. Theme: a leech attaches itself to the opponent, a vampire just attacks and steals. This is my logic.
