Tezeret, Perfected Esper

At the beginning of each upkeep, you may
untap up to two target artifacts you control. If
they are not creatures, put three +1/+1 counters
on them, they become creatures in addition to
their types.
Whenever one or more artifacts you control deal
combat damage, proliferate.
