Blood Clock
This is an intersting card, but not one that
instantly thrilled me. I probably initially
looked past this card because, when a new set
comes out, I always think about limited play
first, and this card has no real value in
limited play. However, this card offers two
interesting ideas for constructed. It's
interesting that your mono-blue control opponent
would have to do what he doesn't want to do,
return one of his permanents to his hand each
turn. Mono blue control players don't have much
in play except for
untapped Islands and they usually don't like to
pick those up. This card gives you a neat way to
return a creature to your hand each turn that
might have an interesting coming-into-play
effect.
Tic Tic Tic...Blood Clock is useful to decks
that want to play and avoid another nasty
"During your upkeep" or "During each
upkeep" effect. You use Blood Clock to
return that permanent to your hand to avoid
its effect.
It does cost 4, so it would best be utilized
by control decks. In limited, it's not
generally going to be useful. In casual,
it's something to use if you have the need
for its ability.
