Well since my edits were cut and summarized I'll include the important math of this item here: This item will pay for itself after 25 minutes and 30 seconds; however, if you only consider the cost minus the amplifying tome, it actually pays for itself in 11 minutes, and it will continue to generate 300 gold every 10 minutes. This means that Kage's Lucky Pick is only practical in the following cases:

1) You plan to build a Deathfire Grasp at some point. In which case, the cost of Kage's Lucky Pick is essentially 0g because you would need to pay for it at some point no matter what. In this case, it's best to buy Kage's Lucky Pick as soon as possible, because 100% of the time spent with it equipped is profiit.

2) You had already bought the Amplifying Tome as a starting item, and you don't need it to build a future recipe. In this case, you can simply subtract the cost of the Amplifying Tome as described above. Alternatively, if you were planning to sell the Amplifying Tome at some point, using it to build Kage's Lucky Pick means you'll lose out on the 305g sell value, so it would in fact take 21 minutes and 10 seconds to pay for itself.

3) You sell Kage's Lucky Pick later in the match. In this case, as long as you meet the conditions in case 2, it will pay for itself in 12 minutes and 46 seconds; however if you still need to buy another Amplifying Tome for a future recipe, it will no longer be worth it.
