Michelangelo's Technique — ruling 1

If a card in your library has {X} in its mana cost, X is 0 for the purpose of determining its mana value.

Michelangelo's Technique — ruling 2

Although a creature put onto the battlefield this way is attacking, it was never declared as an attacking creature. Abilities that trigger whenever a creature attacks won't trigger when that creature enters attacking.

Michelangelo's Technique — ruling 3

Spells can only be cast for their sneak costs any time you could play an instant during the declare blockers step on your turn (after your opponent has decided whether to block).

Michelangelo's Technique — ruling 4

If a creature spell's sneak cost was paid, the creature it becomes enters tapped and attacking the same player, planeswalker, or battle as the creature that was returned to its owner's hand to pay its sneak cost. This is a rule specific to sneak; in other cases, when a creature is put onto the battlefield attacking, that creature's controller chooses which player, planeswalker, or battle it's attacking.

Official card text

Sneak (You may cast this spell for if you also return an unblocked attacker you control to hand during the declare blockers step.) Look at the top eight cards of your library. Put up to two creature cards with total mana value 6 or less from among them onto the battlefield and the rest on the bottom of your library in a random order.
