Just taking a look at your red creatures, The Bushido keyword should have a number after it, such as Bushido 1 or Bushido 3. I think you were going for Bushido 1 on each of those creatures (+1/+1 when blocking or blocked).
Castle Toppler seems overpriced for its effects. Most 4/4 dragons cost slightly less than Castle Toppler and have much better effects. Take Freejam Regent or Glorybringer. Both have much better effects than Castle Toppler for the same or less cost. I understand how the second effect ties into its flavor, but it's a very specific buff for a very specific situation, and it shouldn't factor much (if at all) into the card's CMC. Perhaps take it down to a CMC of 5, or make it a 5/4 or 5/5 creature, or even give it an artifact destruction effect (that would really work with the flavor).
Also Consummate of the Flesh's second effect should read as such: "When Consummate of Flesh attacks it gains +X/-X, where X is the number of creatures that the defending player controls that exceeds the number of creatures you control. (If the defending player does not control more monsters than you, then X equals zero.)" I found this to be a very interesting card. I would actually like to see this effect on a card with less power and toughness and with a lower CMC, since it would become much more useful.
I just noticed that you gave Bushido to creatures with Intimidate. Bushido only activates when a creature is blocked or blocking. Preferably, these creatures would not be blocked, making Bushido irrelevant. I understand that you want to plan for the situation in which they do become blocked, but Bushido just seems tacked on. It doesn't work flavorwise; Bushido is mostly associated with Samurai, not with wild animals.
