Is R&D actively looking to add good, safe build around reprints like Restoration Angel, Ezuri Renegade Leader, Elvish Archdruid, and maybe even Snapcaster mage to add to the Pioneer card pool? I love modern and WANT to love Pioneer, but it feels so watered down and missing some fun and powerful (yet not broken) cards like the ones above. A) are you actively looking for opportunities to reprint? B) are they more likely to happen in a core set (doesn’t care about a card’s plane) or return sets?

We’ll keep making cool new cards and some of them will be build-arounds, but a format half the size of another format will definitionally be of a weaker power level.

Was there a reason why Restoration Angel should not flicker angels?

Powerwise she couldn’t flicker herself so we decided to solve the problem with a flavorful tweak keeping her from messing with other angels.

Are flicker/blink effects (à la Restoration Angel) securely in white's slice of the color pie, or does it bleed into any other colors at all (namely blue)?

Flickering, as we call it, is in both white and blue.

What happens to the booster pack placed under Stocking Tiger if it is flickered by Restoration Angel, or other related effects? Do you need to replace it with a second sealed booster? Does the original booster cease to exist, or can I open it anyway?

The sealed booster pack goes back to where it came from (still sealed) and when Stocking Tiger comes back you get a sealed booster which could be the one you just had under it.

If you guys gave Restoration Angel Flash you could give Red Snapcaster Mage Flash.

White is secondary in flash, but red is tertiary so yes we could give it to red (and we occasionally do).

Your "why we make bad cards" articles have been great. Based on the recent complaints about Thragtusk, Snapcaster Mage and Restoration Angel maybe you should do a "why we make good cards" article too? : )

I’ve had a similar thought. It’s on the “short” list.

Now that we've seen Angel of Serenity, was Restoration Angel's unusual "non-Angel" clause put in with AoS in mind? Flickering AoS with its ability on the stack would be brutal indeed.

“Non-angel” was put on with Restoration Angel in mind.

Can we ban Innistrad block from all constructed formats? The lack of respect for power level ruins the game. Restoration Angel, Snapcaster, Delver, Huntmaster, all make me never want to play any format they are legal at this point.

If I had to rank blocks based on power level, I’m pretty sure Innistrad doesn’t even break the Top Five.

Rather often you say that "Land destruction is unfun, so we weakened it a bit." (paraphrased.) Why then do you keep printing Acidic Slime? A Stone Rain for 1 more mana with an additional target option and a 2/2 deathtouch body seems like its too good, especially with flicker effects running around. It's not uncommon at my LGS to get completely blown out by Acidic Slime+Restoration Angel+Phantasmal Image starting on turn 3 or 4. At least Stone Rain is harder to copy.

One more mana means a lot when we’re talking about land destruction. EDIT: It’s been correctly pointed out that Acidic Slime is two more mana.

Colours are defined by their weaknesses. What are White's weaknesses? They have fantastic small creatures (Thalia), midrange (Mirran Crusader, Restoration Angel), and fatties (Elesh Norn). They tend to have multiple board-control spells at a time (Terminus, DoJ, Planar Cleansing), and they can stop any kind of permanent (O-Ring's most common answer? Another O-Ring). They have Flying, First Strike, and Lifelink. They can play a slow control game or fast aggro equally well. Isn't W too versatile?

White’s reliance on the group while its strength is also its weakness. A single Pyroclasm can wipe out white’s entire army. Also, as I’ve explained, white’s reluctance to kill leaves it open to having the same threats return. White’s game is also very battlefield centric not allowing it to have tools that other colors get.
