What if Mtg Cards Were in Hearthstone and Yugioh | Happy Holiday Cards 

Good luck getting the counters on the Yu-Gi-Oh! Bog Humbugs because the first successful direct attack asks you to hum a whopping 600 notes! XD

i just wanted to comment that the channel name is immaculate for a tcg based creator

Yule Ooze would definitely be "Destroy another friendly minion" as it specifically cannot destroy itself in the magic card so should not in the HS one either

Small correction: Mass Hysteria has been errata’d to function identically to this version of Season’s Beatings after interactions were discovered that allowed the old version to go infinite under certain circumstances and kill your opponent instantly.

IMO a better way for Fruitcake Elemental to be implemented would be "If you have 3 or more unspent mana at the end of your turn, give Fruitcake Elemental to your opponent; otherwise, take 7 damage.", the unspent mana mechanic (usually seen on druid cards) being the closest we have to "paying" mana for something, and the idea behind Fruitcake Elemental's ability is that you want to give it to your opponent BEFORE the end step, but after the attack. Season's beating ISN'T fighting or attacking. The way SB is worded, a creature can get out of the Family Gathering without being damaged at all; ex: you have four 1/1, the first three damage the fourth one, and the fourth one damages only the third creature, meaning that the two first 1/1 gets out unscathed (unlikely but far from impossible). The way you worded it, there would be none left as the first two attack the latter two (or whatever permutation) and they ALL die, always. Honestly, you could literally take the text as it is and change the game-specific words to make "Your opponent's minions each deal damage equal to their Attack to another random enemy minion." and it works as it is. Ooze's abilities are fine, anything more and the text overflows and paying for regeneration is not something easy at all to implement in Hearthstone. There could be some argument about making it random because no card except Titans and Locations can have an effect on the board that makes you choose something once it's already in play, but an effect like the targeted Locations could occur at the beginning of your turn, perhaps. I understand the reduction in cost, as in Hearthstone it's the opponent who choses where the attacks go, unlike in Magic where it's the defending player who chooses, and instants not being something in Hearthstone, it's a LOT more difficult defending your poor 1/1, so it being two mana is more than fair. The Tiger is quite fine, most other representations would be quite clunky and too long in term of text to implement. Don't care much for Yugioh, but they seem good enough.

Am I wrong; but due to the way "Naughty and Nice" is worded, wouldn't it technically be possible for your opponent to negate only the second part of the effect?

Hearthstonrs sylvanas would be a really good magic card i believe
