"When this card is summoned, flip a coin. If the result is heads, you may add one Lvl 5 or lower Machine-Type monster from your deck to your hand. The Deck is then shuffled."
Bit better wording, but still may not be perfect. Good card, but could maybe use a higher ATK or DEF (but not both). I'd give it an 8/10...

OCG fix: [i]Once per turn, you can toss a coin. If the result is Heads, add 1 Level 5 or lower Machine-Type monster from your Deck to your hand.[/i]

Um, the effect can be effective. But its stats make it seriously UP, I would make it 2000 at least.
A 6.7/10

It's alright, but I see much use for it.

If you would use it for "[b]Cyber Dragon[/b]", you wouldn't need it, as you can use 3.
Plus "[b]Gadgets[/b]" make good searching cards for Machines anyway.

If it's for "[b]Machina[/b]" monsters, then I would say "[b]Machina Gearframe[/b]" is a lot better.
"[b]Scrap Recycler[/b]" is also a handy drawing card, though it doesn't search.

Plus it's a heads/tails effect, I really wouldn't risk it, I'd just put the Machine I want to use in the Deck instead of it.
