Otiro, Octoren instigator

if you would create a token while you already
control a token with the same name create twice
that many tokens instead.
{1}{b/r}{b/r},create a 1/1 Octoren creature token with
merge 8(if you control eight or more creatures with
merge you may sacrifice all but one of them if you do
put seven +1/+1 counters on this creature).
Octorens are very useful for the Bloodblade.
