Point Extraction

When Point Extraction enters the battlefield,
create 6 0/1 blue Aquarq tokens with Inanimate.
Dwarf creatures you control gain "{t}: Attach a
non-attached Aquarq token you control to this
creature. You may pay up to X colourless mana
(where X is the number of Aquarq tokens
attached to creatures you control) to create that
many 2/2 white Glyphid Grunt tokens."
During any end phase where all Aquarq tokens
you control are attached, destroy all Aquarq
tokens and exile Point Extraction.
