Beast Tender Dryad

Cascade (When you cast this spell, exile cards from
the top of your library until you exile a nonland card
that costs less. You may cast it without paying its
mana cost. Put the exiled cards on the bottom in a
random order.)
Draw a card for each Beast creature card you cast while Beast Tender Dryad is on the stack. Those creatures enter the battlefield with a +1/+1 counter on them.
