Based on what I've seen with Paladin buff decks as I'm at work I would suspect the following
At the end of your turn you'd generate a minion that undamaged would get 11 attack. The +4 variable that generates the additional attack on its owners turn would be added to this. You're manipulating the base stat that this modifier is applied too, not the modifier itself or its trigger condition
As above, i'd expect a 3/3 that on the owners turn turns in 7/3. I'd see this as base stat manipulation rather than playing with the +4
This is a good one! I'd suspect that as the Tar Lord's +4 is applied as soon as the owner's turn begins, your Pint-Size Potion is applied afterwards, which simply takes -3 off the amended attack value. I CAN see significant error for my being wrong depending on how the Hearthstone client applies the sequence of events so I'd love to know this too.
More than willing to cede to peers that have tested these scenarios.
If there is an undamaged Tar Lord on enemy's battlefield,
1. If I cast Inner Fire on enemy's Tar Lord, what will happen?
2. If I cast [card]Dark Conviction[/card] on enemy's [card]Tar Lord[/card], what will happen?
3. What will happen if I use Pint-Size Potion?
4. What will happen if I cast Crazed Alchemist's Battlecry on Tar Lord?
1. 11+4/11 Tar Lord
2. 3+4/3 Tar Lord
3. 5-3/11 Tar Lord
4. 11+4/4 Tar Lord
