That's a strong interaction, as it basically reduces the Escape cost to 1 so you get to go looting through your deck as many times as you had cards in your yard. But - where does that end up getting you? Whats' the payoff? Your yard ends up empty so you're not going to Yawgwill anything. You need to have Tendrils in hand or available when you do this. It seems like you're converting cards in your yard into storm, which isn't bad but isn't something that storm decks have trouble doing already. On the other hand, Search is a better card overall than Freeze, so that's nice.
Whats your analysis on this?
