Well that can work if you're aiming for late-game. However mid-game assassins fare better, especially since they tend to snowball early. I'd prefer snowbally assassin over typical mage, since the power spike is highest for them at mid-game, falling off the longer game goes. As an assassin you can't afford to make mistakes, and the probability of making a mistake is higher the longer game goes on. This is what I think might come later on (gonna type the scenario of kinda perfect-played game):

A team (let's call them team A) has got typical mid mage as a support and assassin on middle lane (with the rest being tanky top and jungle with typical ADC). Marksman/woman and assassin get money for farm and kills. Game proceeds to middle stage, however enemy team (team B) manages to play safe and victory can't be decided. Assassin is at his strongest, however he starts to fall off since team B can afford for defensive items now. There's now a stalemate, game reaches late-game phase. Meanwhile Assassin and Marksman/woman reached their full builds. Support farmed when he could without delaying their builds and has, let's say, 4 items completed. He starts to farm, gaining power. Meanwhile enemy used let's say Sona, who's best used early in the game for her poke and zoning - later she can only stay in the back to jump in and use Crescendo, not really commiting to the fight (in other words, deal damage). However out mid mage played as a support too can't commit to the fight completely, since it's too dangerous for him to go agains 6-items. With the utility he possess, he ensures partian safeness of his team's (team A's) marksman/woman. No team can reach definite upper hand yet. Game goes on and every member now has 6 items in their builds. Team B has lesser damage output than Team A, because of their supports. Let's summarize it up:

- Team A: Tank, Bruiser, Assassin, Mage and Marksman/woman.

- Team B: Tank, Bruiser, Mage, Support and Marksman/woman.

Support provides buffs to his team, while Mage commits to the fight in order to score an Ace. Team A holds the upper hand in terms of damage, while Team B struggles to protect their valuable damage-dealers. However, Team A can sacrifice one of them in order to dive deep and wreck havoc on enemy backlines, with Assassin taking out Team B's Marksman/woman. Team A gains the upper hand, which leads to won teamfight and in effect - the game.

'''Note (once again) that this is just a scenario, and game doesn't have to play out like this. Not everyone can play perfectly and much is based on luck and teamwork. This is just a theorycrafting.'''

Sorry for making it such a long wall of text... like most of my posts/replies. :-)
