Sliver Sympathy

When Sliver Sympathy enters the battlefield,
create one 1/1 colorless Sliver creature token.
Enchanted creature has Vigilance and "this
creature gains whatever a Sliver under your
control would gain from other Slivers."
"Invasive species bring abrupt change. Those who
survive become ecoindistinguishable from natives."
- Wrinda, Dean of Biology
