Dune-Brood Elemental

Dune-Brood Elemental's power and toughness
are equal to the number of lands in play and in graveyards.
Whenever Dune-Brood Elemental survives
damage, create that many 1/1 colorless Sand
creature tokens with "{t}, sacrifice this creature:
add {c}."
Dune-Brood is the earth given form- if only barely.
