Implements Osgood, Operation Double

[JayDi85]

For info: for new cards add comment ref to original set implementation issue like “Part of #10653”. So that PR will be visible in related links of the set’s issue.

Current scryfall bot do not support [[card name]] processing in title, first PR message or PR review, so I recommend to duplicate it as [[Osgood, Operation Double]] in new comment - so bot will add card description here.

Osgood, Operation Double - (Gatherer) (Scryfall) (EDHREC)

{2}{U}{U}
Legendary Creature — Human Alien Shapeshifter
2/2
When you cast this spell, create a token that's a copy of it, except it isn't legendary.
{T}: Add {C}. Spend this mana only to cast an artifact spell or activate an ability of an artifact.
Paradox — Whenever you cast a spell from anywhere other than your hand, investigate. (Create a Clue token. It's an artifact with "{2}, Sacrifice this token: Draw a card.")

Card logic is fine except few small fixes

[JayDi85]

If you copy or fix code from another card with same ability/effect then must copy/fix all places with same code (even if you don’t understand the original logic). The main idea: same ability/effect must use same implementation code.

[balazskristof]

I'd rather not touch this. Cargo Ship and other cards seem to work fine; I can use the mana to activate other activated abilities, like Unearth.

[JayDi85]

Nope, it’s about allow to activate one time only (activated sets true on activate call).

I’m not sure why it used or required. Maybe for good playable calculations or some workaround from multiple instances, etc. But it’s better to keep same code.
