Is this already a thing?

This must have been done before, but I so rarely find my own combos so I got excited...

{goblin welder}
{intruder alarm}
{runed servitor}
Any artifact creature in gy.

If oppenent drew any extra cards (assuming each has 60 card deck), make everyone draw out their decks

Or use {cathodion} or infinite colorless.

{intruder alarm} is so broken. It's like half of all magic cards go infinite with it.

{intruder alarm} is so broken. It's like half of all magic cards go infinite with it.

I remember the first time I had it. I missed the second line, so I was like: "Cool, {Stasis} for creatures.
It wasn't until I played it my playgroup corrected me. I was "abusing" it in a vigilance swarm deck (not a keyword by then, but it had untap effects and things like {Serra angel}.
Worst case of didn't read card ever.

Using Intruder Alarm is basically cheating when coming up with combos. Same with {Ghave, Guru of Spores} and {Mana Echoes}.
