There's no greater feeling in Magic: The Gathering than ripping the exact card you need off the top of your deck at the beginning of a turn
Creature Artifact - Construct Color tag templates(None) Crystalline Giant At the beginning of combat on your turn, choose a kind of counter at random that this creature doesn't have on it from among flying, first strike, deathtouch, hexproof, lifelink, menace, reach, trample, vigilance, and +1/+1
If you choose a creature you control with a +1/+1 counter on it, you put another +1/+1 counter on it
Looking through Gatherer for all of the cards that have scry, it's clear that if you were able to get both of these out, a deck with a heavy scry strategy (scrytegy?) could draw a ridiculous number of cards
