Grapnel Launcher is one of my favorite new cards.

For 3 ER you get a pseudo-Ready, 1 THW and a patrol / crisis bypass. If you can benefit from the bypass this effect is above rate, otherwise it is on rate. In a vacuum, it is okay. If your hero cares about basic activations though, the value goes up.

This becomes a build around tool for a number of heroes opening up some interesting lines; Black Panther, Cable, Iceman, Jessica Jones, Jubilee, Nick Fury, Nova, Psylocke, Quicksilver, SP//dr, Spider-Woman, Wasp, X-23 all can benefit from a free basic thwart action timed when you want it.

The restricted key word is unlikely to matter as the only other restricted card in Justice is Sonic Rifle.

• Restricted. May mess with some heroes' space for weapons, and with Sonic Rifle.
• • Can be stored for when its needed, yet restricted has to be taken into account
• ITEM instead of WEAPON, can be grabbed with jubilee's Shopping Spree
• 3ER for a +1 THW, but most importantly, an emergency thwart that ignores Patrol/Crisis
• Sinergy with cards that requires you to do a basic thwart (like Making an Entrance and Justice Served)

All that considered, its still 3ER. Assuming a base 2THW, this is a save-for-later 3THW (which is in be lower middle part of the cost efficiency for thwarts). However, with having a base 3 or 4 Thwart (Innate Perception, Heroic Conditioning), this cards becomes an expensive but worthy asset, if the above conditions dont mess with your deck and with your hero.
