Summons a card from opponent's deck

This card lacks something. And I think I know what it is.
When you see "summons a ..." in card effects, you think it will use the same draw rules as Mage guild (9C/7U/9R, chances to draw: 36% - 28% - 36%) or Lady Ellena (15C/18U/11R, chances to draw: 34,1% - 40,9% - 25%). But instead of these rules Baku uses a standard draw, like Militia. The only difference is, Baku uses opponent's deck while Militia uses yours.
That makes Baku more of a deadweight than a card you want to play. There are better Illusion chain finishers (Shadow wolf, Faceless, Doppleganger, Magical defense), and there are better ways to use gems for Beast decks (Wolf spirit, non-Beast supportive cards).
Would Baku be balanced or overpowered if draw rules for it would be changed from standard to summon? To be honest, I don't know. But I'd like to try it and see what happens.
What do you think?

So right now it should state "Draws a card from opponent's deck" instead of "summons"? I didn't even realize that flaw tbh.

Yes, something like that.

The code indeed works as a normal draw, I didn't notice that.
My intention, when I proposed the concept, was to give a 33,3% chance to draw a rare (same for common and uncommon obviously) to boost Illusion decks, pretty weak at the time. Now Illusion is stronger but I think this card should change as NG suggested, maybe raising the cost a little.

I, too, assumed an equal chance to draw any of the 45 cards rather than the standard draw odds given the way it was worded. (I also didn't know the code well enough to see that it was functioning that way.)

Actually i'm not sure about the code, but I see a 'DrawCardRandom' line that is absent in other summoning cards (they have 'DrawCardList' instead).
I assume that that 'DrawCardRandom' is a guided random, with fixed probability. But don't trust me: I'm a copy-paste programmer.

Militia has this line:
$mydata->Hand[$mode] = $this->DrawCard($my_deck, $mydata->Hand, $mode, 'DrawCardRandom');
So I guess it means standard draw imitation.

It's a standard draw currently.

Is it intended?

Yes, it is. But I'll will analyze the proposed changes in the next update ;-)

I don't think it would be overpowered to have a 1 in 3 chance that this draws a Rare from the opponent's deck. It's a gamble with a high chance of resulting in a dead draw, though possibly useful combined with replacing cards or Vulture or Legend keyword. Considering that the Illusion keyword means that the player may be guaranteeing a Rare anyway with the trigger, we should just examine how this card functions outside of an Illusion deck. If summoned into play via the Beast keyword, I think the current chance that it draws a Common from the opponent's deck makes it look like garbage. I mean, you have the same chance at a Rare by discarding it, and in that case it's at least one that fits your deck.

I didn't know Baku had the standard card draw mechanic either. In that case, I definitely suggest buffing it in some way. In my opinion, Baku as it is now is usually worse than a 0/6/0 Beast + Illusion card with 6 attack and no other text. By comparison, Wolf Spirit (0/4/0 Beast + Illusion, 5 attack) would probably be a better card than Baku, even if it never gave +3 recruits. Druid might be a better card for comparison, since it has the same cost and a summoning effect, in exchange for 1 less cost. However, Druid's summoning effect has an excellent chance at a rare card (at least, when used for a Nature card), and its keywords fit well with both Restoration and Nature decks. Beast often won't be useful in decks that use Baku.

Note that these comparisons don't necessarily imply that Baku is bad, especially since Druid and Wolf Spirit are both excellent cards in decks that can use them. I would, however, still argue that it is inefficient and its text is often a drawback, which makes me hesitant to ever include it in a deck. There are much better Illusion commons, and Illusion decks generally don't need lots of common Illusions cards. Beast decks generally don't want to clutter their hands with mediocre non-beast cards.

On the other hand, changing Baku to standard summoning probabilities (1/3 common, 1/3 uncommon, 1/3 rare in this case) might make Baku too powerful. Summoning cards (especially common ones) in MArcomage are, in general, very strong and probably usually undercosted for their power (though that is another topic to discuss). The fact that its cost is gems, the primary resource of Illusion decks, should probably make Baku balanced in Illusion decks, but if it is too strong for decks that are not starved on gems, we might see it taken in many decks, regardless of their type, due to its relative strength and (sort-of) flexibility.

I won't say it's necessarily bad, because we already have similar card - Princess of elves. And it doesn't feel too strong at all.
And yes, I would never take this card into Beast deck in its current state. It needs something like 7-8 attack and 3-4G cost for Beast deck.
