Possible idea for a champion?

Over the years, this game has gotten new champions that have interesting concepts in their kits. ; who can disguise and create illusionary copies of herself, even though I want to scream whenever I play . (and a space dragon is cool enough concept for a champion as well.) and others I find to have interesting ideas behind them are to name a few. Though every champion has a reason that they are in the game. But I have an idea for a new champion, one unlike any I have seen here?

Stealth is fun, there are plenty of champions that have stealth mechanics, but none of them use stealth for reasons aside from assassination. A champion that while being unable to 1 v 1 early on, could instead play a game of hide and seek? This champion would not have mobility, instead would have to evade getting killed by juking, setting traps, summoners spells, and relying on clever routing to divert the enemies' jungler and anyone else who may want to get to them. So this is what I have so far, and hopefully this could spark discussion on possible items, skills, and interactions with certain strategies.

Name-

Passive- Tricked! Gain movement speed when an enemy champion triggers a trap (maybe even a fair reduction in cooldowns.)

Q- Tripwire Toss out two hooks to form a wire that slows champions that walk over it, this should have a limited number of charges, and has to be used twice to create a line. (This works similarly to what has.)

W- Spike trap Place a spike trap on the ground that deals damage once to anything that steps inside it's range, These remain hidden from normal view like a Teemo mushroom, but can be found with wards. These traps also have charges.

E- Blowback Trap This is part of your trap-setting, you can probably guess that this deals damage and knock anything that triggers it into a direction set by the player, can also be used for mobility purposes for you or an ally. Maybe this could make enemies vulnerable and take extra damage from the spike trap.

R- I am still barnstorming a potential idea for an ultimate that works well with this kit, it could be similar to but I want something different.
