I think Pro Contacts is getting way too much hate for what it is.
... I think comparing it to MO isn't correct, since the MU and program trashing liabilities won't hinder aggressive running.
Well, I do think its better than Magnum Opus. But I think Opus is terrible now, and you can do a lot better with a deck full of Diesel, QTime, and burst economy cards.
Comparing Pro Contacts should be compared to using Diesels and QTime, because its a draw bonus. It makes your natural draws worth +$1. But it costs 5, and is a resource, so it forces you to care a lot about tags.
If you install pro Contacts, and draw 25 cards with it, thats pretty good. What is the alternative way to gain +24 cards?
Pro Contacts: 26 clicks = Net: +24 cards, +$20.
Play 2 Diesel, 2 QTime, and draw 12 cards: 16 clicks = Net: +24 cards, -$6. That leaves me 10 clicks to try and recover $26, which I probably cant do.
Well, that does look to be evidence for Pro Contacts having a place. It has three problems:
1) Puts you in a big hole to start.
2) It doesnt work well with Diesel/QTime, because if you use those to draw, you wont be using it enough to make it pay off.
3) Tag vulnerability.
However, in a deck that doesnt use other draw cards, AND doesnt want tags, it could be decent. Its kindof like a big Underworld contacts. Its more expensive (but no link requirement), and tends to net you more like $1.5 a turn. I guess that might be okay.
