#3. The block from two years ago (Return to Ravnica in this case) and last summer's core set (Magic 2014) rotate out at the same time when the new block (Khans of Tarkhir) becomes standard legal in late September/early October.
A 30% increase in difficulty means the network was finding blocks 30% too fast over the last 2015 blocks so as a result, your profits (assuming no other miners join or leave the network) will be about 23% (1 - 100/130) less. For example, 1 GH/s nets about 0.00098431 a day at the current difficulty. With an increase of 30%, this would mean about 0.00075716 per day, 0.00098431/0.00075716 is about 130%. However, with all the mining equipment being added between blocks, it's likely you'll make a lot less.
