However, if a card states you can have as many in your deck as you like, you can have multiple of those cards
The problem is that a 2/2 (even a 2/2 with flying) can be outclassed fairly quickly, so delaying Vexing Gull trades its early game relevance (pecking in for damage) for mid-game value (when you might be behind in the race or not be able to attack with Vexing Gull)
Its Chaos Control ability grants split second to your spells if you spent artifact mana, so its nearly impossible for your opponents to interact with them
Activating the last ability multiple times won't cause you to gain more life

That doesnt exactly synergize in a construct setting, but where there are other constructs there are probably other noncreature artifacts
