One thing that tends to be weak in strategy games is "opponent's choice" effects, where an ability has multiple possible effects and an opponent chooses which is resolved. Usually, each effect is stronger than what you would normally get for a card with that price, but in practice these cards are often quite weak.
For instance, the Magic: the Gathering card "Book Burning" looks quite strong in theory, as it either does 6 damage or mills 6 cards (both strong effects that might well be worth more than the card's cost, since this was a set where having cards in your graveyard was quite relevant). However, in fact it is quite weak, because in practice you will always get the effect that is less relevant; if the opponent has life to spare they'll take damage, and if the mill is no longer relevant they'll let you mill instead.
This pattern holds true across multiple games. In Legend of the Five Rings, Levy is similarly weak despite the fact that a card that did only one of its effects would likely be overpowered, as one effect or the other is likely to be much less relevant at any point in the game and the opponent can always choose the less relevant effect.
Interestingly that's actually quite disputed -- you linked to a reprint of the card that displays as being rated 5/5, but the original printing of the card is actually rated 3.455 out of 5.
(That said, it's certainly better than Book Burning!)
I remember seeing a deal from a bank where the bank got to chose whether to pay a fixed interest rate or a variable one and either path looked like a good deal but the fact that the bank would chose meant you would always end on the wrong side of the market. I wish I could remember the exact promotion.
